The function of citation is to make the argument conclusive and sufficient, to make it more persuasive and enlightening, and to make the language concise, implicit and elegant. When writing an article, you intentionally quote ready-made idioms to express your thoughts and feelings and explain your opinions on new issues and new principles. This rhetorical method is called quotation.

1. It can make the language expressed concise and concise; lively and infectious. For example: So I gave up my dead look and started joking with peace of mind, but unexpectedly, I immediately ran into trouble with serious people: I said that I had "disappointed" them. Of course I knew that it used to be the world of the old people, but now it is the world of the young people. But unexpectedly, although the people who govern the world are different, the ban on talking and laughing is also the same. Then, I have to keep pretending that I am dead. Wouldn’t it be painful to keep pretending that it is only after death?

2. Expressions and expressions are very helpful for reasoning, providing strong arguments for one's own views and opinions, and enhancing persuasiveness. Such as: Isn’t it? Even though Shanhaiguan is a fortified and dangerous place, there are records of it being breached; and Wu Sangui's attempt to lure the Qing into the pass was even more self-defeating. Didn't Dorgon's cavalry swarm through the open gate and sweep across the Central Plains? "The six armies who mourned were all in good condition, and the anger turned into beauty." Wu Meicun's "Yuanyuanqu" expressed the indignation and hatred of the patriots towards Wu Sangui at that time. Although historians still dispute whether Wu Sangui's motive for surrendering to the Qing Dynasty was for the "beauty", it is a fact and a lesson that Xiongguan was betrayed without defeating himself.

3. Make the arguments conclusive and sufficient to enhance your persuasiveness. For example: I often quote some famous quotes. Famous quotes are classic works and authoritative remarks, generally including famous quotes, aphorisms, aphorisms, famous lines from ancient poems, etc. In argumentative essays or comprehensive writing styles, the author often quotes famous quotes as theoretical arguments to demonstrate his or her point of view, using the argument as the commander and always serving the argument. Generally speaking, quoting famous quotes at the beginning of an article can achieve the functions of outlining and guiding the entire article, making it fascinating, and setting the tone for the entire article.

Quoting famous quotes in the article can make the arguments conclusive and sufficient, enhance persuasiveness when explaining problems and clarifying opinions, and has the functions of highlighting the center, being inspiring, and refining the language.

4. Quotes are very helpful for reasoning and expression, providing strong arguments for your own views and opinions, and enhancing your persuasiveness. It has the finishing touch, can enlighten people's minds and sublimate the theme. For example: "New Theory of the Six Kingdoms" by candidates from Tianjin and "New Biography of "The Peacock Flies Southeast"" by candidates from Jiangsu. "The New Theory of the Six Kingdoms" found a breakthrough in its intention from Su Xun's "Theory of the Six Kingdoms": "The destruction of the Six Kingdoms was due to the lack of integrity of the kings of the Six Kingdoms." point of view; then closely follow "integrity" to analyze the historical facts and demonstrate the point of view; and finally use Du Mu's famous sentence in "Afang Palace Fu" to "The lessons of the past are the teachers of future generations. Wouldn't it be more regrettable for future generations to lament and fail to learn from them?" "It makes people sad" ends; the article has profound intentions, unique analysis, and shines with the light of personality.

5. It is helpful for readers to generate associations or echoes while reading, to achieve the effect of bringing out the old and bringing forth the new, enhancing vividness, or being humorous and enhancing the image. Quotation is a common rhetorical method that expresses one's thoughts, feelings or opinions by intentionally quoting poems, famous examples, aphorisms, etc. in articles.

6. Quoting poems in the article can make the article more beautiful and colorful. For example, the article "Past Events Yiyi" quotes the verses in "Poetry of a Thousand Families" that praise the scenery of the motherland, showing us the scenery of spring, summer, autumn and winter: one who wrote about spring has "everything is always spring" (interpretation: the spring breeze makes flowers bloom, and everything is colorful. All are spring scenery). The description of summer scenery includes "The green trees are dense and the summer is long" (interpretation: The green trees are lush and dense and the summer is long), and the autumn scenery is "The young girl can withstand the cold, and she fights in the frost in the middle of the month" (explanation: Frost The divine green girl and Chang'e in the moon are not afraid of the cold, competing for their beauty in the cold moon and frost, competing for their beauty in the cold moon and frost, competing for their pure and beautiful appearance). One of the writers who wrote about winter is "The plum blossoms and snowflakes are fighting for the spring but they are not willing to fall, so the poet spends money on commentaries" (paraphrase: both the plum blossoms and the snowflakes think that they have all the spring beauty, and neither one is willing to admit defeat.

It is difficult to break a poet and write a critical article). These poems are like beautiful pictures and close-up shots, leaving a deep impression on readers.

7. Quoting poetry at the end of the article kills two birds with one stone. It can not only summarize the full text, but also deepen the theme. For example, "The Pear Blossoms on the Post Road" quotes Lu You's poem "The Pear Blossoms on the Post Roads are blooming everywhere" (interpretation: Pear blossoms are blooming everywhere along the spring breeze) from Lu You's "Wen Wujun Prefecture has returned to Xijing" (interpretation: the spring breeze is in full bloom everywhere), which is the finishing touch and structurally echoes the title. , deepening the theme in content, symbolizing the spirit of Lei Feng being carried forward everywhere in China.

8. It is thought-provoking. It plays the role of finishing touch and sublimating the theme in the article, and has the effect of blending water and milk. Famous quotes are classic works and authoritative remarks, generally including famous quotes, aphorisms, aphorisms, ancient poems, etc. In argumentative essays or comprehensive essays, authors often quote famous quotes as theoretical arguments to demonstrate their opinions, using arguments as the commander and always serving the arguments. The function of citation is to make the argument conclusive, more convincing, authoritative, enhance literary talent, enlightening, and the language is refined, implicit and elegant. Quoting famous quotes at the beginning of an article can provide an outline, lead the whole article, be fascinating, and set the tone for the entire article. Quoting famous quotes in the article can make the arguments conclusive and sufficient, enhance persuasiveness when explaining problems and clarifying opinions, and has the functions of highlighting the center, being enlightening, and refining the language. Quoting famous quotes at the end of the article can add the finishing touch to the entire article, enlighten readers, and achieve a harmonious effect.

Introduction to the meaning of quotation:

Quotation refers to a rhetorical method of quoting ready-made words, such as poems, aphorisms, idioms, etc., in speaking or writing to express one's thoughts and feelings. Quotations can be divided into two types: explicit citations and implicit citations. Explicit citation refers to directly quoting the original text and adding quotation marks, or quoting only the main idea of ??the original text without adding quotation marks, but indicating the source of the original text. Hidden citation means not stating the source of the quotation, but weaving it into your own words, either quoting the original sentence, or just citing the general idea. The use of quotations can not only make the article concise and concise, but also help to express emotions; it can also increase literary talent and enhance expressive power.

The meaning of quotation:

Explicit citation refers to directly quoting the original text and adding quotation marks, or only quoting the main idea of ??the original text without adding quotation marks, but indicating the source of the original text. Hidden citation means not stating the source of the quotation, but weaving it into your own words, either quoting the original sentence, or just citing the general idea. The use of quotations can not only make the article concise and concise, but also help to express emotions; it can also increase literary talent and enhance expressiveness. There are two types of borrowing. One is also called "replacing", which means that the original meaning of the original text is neither the same, similar, nor opposite to the meaning to be expressed, but is only related in a certain aspect. It can innovate, enhance vividness, and produce humorous effects. It can also arouse readers' association with the story and enhance the image. Another method is to borrow symbols from mathematics and combine them into a simple formula to express complex ideological content, achieve the purpose of being concise and comprehensive, and have an intuitive and visual artistic effect. Citation explanation:

1. Recommended appointment. "Book of the Later Han Dynasty·Li Ying Biography": "Therefore, I quote famous people from all over the world." Du Fu of Tang Dynasty's poem "Gift to Secretary Supervisor Li Gongyong of Jiangxia": "In the past, Empress Wu of the dynasty cited many favorites." Qing Zhaoyi's "Xiaoting Miscellaneous Records·Bu" "Happy Party": "Therefore, those quoted are people who are eager for success and fame. They are circuitous, slow and foolish, and they are all idle and indifferent."

2. Use other people's examples or words as a basis. Liu Zongyuan of the Tang Dynasty wrote in "Bianlt;; He Guanzi gt;;;": "What is quoted by Wei Yi is beautiful, and the rest is useless." Song Wu Zeng's "Neng Gai Zhai Man Lu·Shi Shi Er": "I even read the quotation by Dou, Then I realized that there is no need to use the principles of Zheng, Wu, and Jiu Shangguan. "Ai Qing's "Preface to Selected Poems" 4: "I quoted...two sentences from Li Bai in the article."

Introduction to the main quotation:

Zhengyong, also known as "zhengyong", means that the quoter has a positive attitude towards the quoted sentence, and is used when the quotation is consistent with the meaning of the original text. Positive quotations are generally used to confirm one's own opinions and express one's thoughts and feelings. It can be either explicit or implicit.

For example:

1. Mr. An is as obedient as that girl. Why is he so stubborn all of a sudden? ...This part of his comes from the ultimate nature. As the so-called hero among children, it immediately means "rich and noble cannot be lascivious, poor and humble cannot be moved, and power cannot be surrendered"; others only say that he is slowly persuading. When the transfer came, who would have thought that he had already made up his mind that he could not change the situation? (Qing Dynasty Wenkang's "Heroes of Sons and Daughters") In the novel, Mr. An's father was accused of poor governance because of two river embankment breaches, and was dismissed from his post for investigation and imprisoned in Shanyang County. Mr. An was so eager to save his father that he never traveled far away. Instead of being obedient like a girl, he decided to travel three thousand miles across mountains and rivers to Shanyang County with thousands of taels of silver to rescue his father. "Wealth and honor cannot be lascivious, poverty and lowliness cannot be moved, and power cannot bend" comes from "Mencius: Teng Wen Gong", which means: "He cannot be tempted by glory and wealth, cannot be shaken by poverty and hardship, and cannot be made by power and violence." " "Nine oxen can't pull it around" is a reference to the proverb. Both quotes illustrate that Mr. An is extremely stubborn at this time. No words or people can change his determination to rescue his father. They are consistent with the meaning of the original sentence quoted, so they are positive quotes. The source is not specified here, it is an implicit quotation.

2. The soul of Qin Zhong went wherever he wanted, and he remembered that no one at home was in charge of housework... so he prayed to the ghost judge in every possible way. Unfortunately, these ghost judges refused to show favoritism and instead scolded Qin Zhong: "You are still a person who has read books. Don't you know the saying goes: 'The King of Hell tells you to die at the third watch, who dares to leave anyone alive until the fifth watch.' We are all in the underworld." He is selfless and selfless, no more caring than you in the world, and has many obstacles." (Qing Dynasty Cao Xueqin's "A Dream of Red Mansions") "The King of Hell tells you to die at the third watch, who dares to leave anyone alive until the fifth watch." It is: "The King of Hell ordered you to die at the third watch, and asked the ghosts to seduce your soul. No one can make you live until the fifth watch." This proverb is a positive quote here, and the author said it through the mouth of the ghost judge, It makes a sharp contrast between the selflessness of the underworld and the selfishness, favoritism, and dark corruption under the feudal political system of the underworld. It expresses the author's purpose in saying this, which is to severely lash the feudal regime in the world. This is both a positive and a clear quotation.

3. There is a poem in "Lu Xiangshan's Quotations" that reads: "Now read at a regular pace, and let go of the unknown parts. Don't be too slow." Then he cited the following poem: Reading Don't be in a hurry, swimming time is more interesting; don't let it go before dawn, you need to think about it urgently. This is what is meant by "reading without asking for a deep understanding." Originally, it does not mean that you don’t ask for a deep understanding, but it does not mean that you don’t want to understand the book. It means that you should let go of the difficult parts first, and don’t cling to them. Maybe after reading the context, you will understand the difficult parts; if you still don't understand, you will have to wait for an explanation later. This meaning seems particularly useful for us young readers. (Deng Tuo's "Yanshan Night Talk: The Secret of Not Wanting Secrets") This text is quoted in three places. The first is that the author quoted from Lu Jiuyuan's "Lu Xiangshan Quotations" "Nowadays, when reading, read at a regular pace, and let go of the unknown parts, don't be too laggy." The second place is a quote from a poem by Lu Jiuyuan: "Be careful not to read in a hurry, as the reading time is long and interesting; you may as well let it go before dawn, but you need to think about it urgently." The third point is "Reading does not seek for a deep understanding." When clarifying his point of view, the author quoted the phrase "A good reader does not seek for a deep understanding" from "The Biography of Mr. Wu Liu" by Tao Yuanming, a famous poet of the Jin Dynasty. The author expresses his affirmation of the sentences and poems quoted above. They are consistent with the meaning expressed in this article. They all say that reading does not have to be too stubborn. If you don’t understand a problem, you don’t have to dwell on it. You have to understand it. No, sometimes the problem is not understood, but time is wasted. Therefore, it is recommended to let go of the difficult parts for the time being, and then slowly clarify them later. This is the method of positive introduction. In order not to cause misunderstandings among readers, the author repeatedly explains "not asking for a deeper explanation" and especially points out that "it seems to be particularly useful for our young readers." The first and second places point out the source, which is an explicit quotation; the third place does not point out the source, which is a hidden quotation.

Introduction to back-quoting:

Back-quoting is also called "back-quoting", which means that the quoter evaluates the quoted sentence and holds a negative attitude, that is, the meaning used is different from the original one. The meaning is the opposite, to achieve unconventionality, or to play a satirical role. Reverse use can be divided into three categories in form. The first type is to copy the original text, and then deny or modify the original text; the second type is to directly change the original text, so that the meaning used in this article is opposite to the original text; the third type is to elicit the main idea of ??the original text, and then raise objections. For example:

1. Confucius said: "Only women and villains are difficult to care for. Those who are close will not be inferior, and those who are far away will be resentful." Women and villains are classified into the same category, but I don't know if they are. Including his mother. Later Taoist gentlemen, on the surface, finally respected their mothers. However, despite this, Chinese mothers are still despised by all men except their own sons. (Lu Xun's "Collection of Nanqiangbei Diao·On Women's Liberation") "Only women and villains are difficult to maintain. If you are close, you will be inferior, and if you are far, you will be resentful." This is a sentence said by Confucius, which means: "In this world, there are only women. It is most difficult to get along with villains. If you get close to them, they will be rude; if you stay away from them, they will be resentful." The author has a negative attitude towards this sentence. He first quotes this sentence and then immediately makes a judgment on it. Putting women and villains together is a great contempt for women. In an era when women were demanding liberation, Mr. Lu Xun went against the grain and spoke loudly for women's liberation.

2. "When I entered the Ancestral Temple, I asked about everything." It has been passed down as a good saying to this day. But when you get on the ship, it’s best not to ask about everything. The waiters’ fear of trouble and laziness are their characteristics. If you ask them, they may say they don’t know, or they may deliberately make fun of you. Fortunately, they treat guests except Everything except luggage is irresponsible. (Zhu Ziqing's "Hai Xing Miscellaneous Notes") The quotation in this paragraph comes from "The Analects of Confucius·Eight Yi", which means: "Every time Confucius enters the Ancestral Temple, he has to ask about everything." The author quoted this sentence to say that the ancients thought it was good Asking is a virtue, but it is later pointed out that it is not easy to ask on a ship. Quoting the original words and changing their meaning is a counter-quotation technique. The above two examples are both directly copying the original words and then denying or correcting them, so they both belong to the first category of reverse use.

3. Don’t flick your crown when bathing in fragrance, and don’t shake your clothes when bathing in orchids. Don't be too clean when you are in the world. The most valuable person is to hide your brilliance. ("The Bathing Son" by Li Bai of the Tang Dynasty) There is a sentence in "Chu Ci: Fisherman" that "a new bather must flick his crown, and a new bather must shake his clothes". Looking at Li Bai's poem again, it is obvious that he used the technique of reverse usage, directly changing "bi" to "mo". The semantic meaning is exactly the opposite, and it belongs to the second category of reverse usage.

4. Oh, my sword is going to bed! I don't want to imitate the frivolous General Li, who used his weapon to shoot at a tiger, but in fact he only shot at a cold, stubborn stone. Oh, my sword is going to sleep! I also don’t want to imitate the pedantic Li Hanlin and use his weapons to cut the flowing water. While cutting, the water flows again. Oh, my weapon is only to hide, my weapon is only to sleep soundly. My weapons are not meant to cut off treachery, for I know that treachery is a pile of cold, stubborn rocks; my weapons are not meant to cut through sorrow, for I know that sorrow is like a steady flow of water. Oh, I'm done! Let my sword go to sleep! Am I like the cunning Emperor Gaozu of the Han Dynasty who killed a white snake with his sword and spread a rumor to deceive the whole world? (Wen Yiduo's "Sword Box") There are three quotes in this section of the poem: "Li Guang shot a stone", "Hanlin cut off the water", and "Gaozu killed the snake". "Li Guang shoots stones" comes from "Historical Records: Biography of General Li": "Guang went hunting and saw a stone in the grass. He thought it was a tiger and shot it. The stone did not have the arrowhead, so he saw it as a stone." It means: "General Li went hunting and saw He thought the stone in the grass was a tiger, so he shot it with an arrow, and the arrow shaft sank into it. When he got closer, he saw that it was a stone. "Hanlin" in "Hanlin Broken Water" refers to Li Bai, who wrote in "Xuanzhou Xie Tiao Tower". There is a poem in "Farewell to the School Secretary Shu Yun" that "cut off the water with a knife and the water will flow again; raise a cup to eliminate sorrow and sorrow will become more sorrowful". "Gaozu chopped the snake" comes from "Historical Records: The Chronicles of Gaozu". Liu Bang was drunk in the lake and encountered a big snake blocking his way, so he drew his sword and chopped the snake into two pieces. Later, he used this as "divine help" to rise up and seize the world. declaration.

The poet quoted the main idea of ??the original text here, and then raised objections, "I don't want to imitate the frivolous General Li", "I don't want to imitate the pedantic Li Hanlin", "How can I be like the cunning Emperor Gaozu of the Han Dynasty", which very clearly expresses the poet's intention.

5. The promulgation office seeks talents and visits ministers, but Jia Sheng’s talents are even more unmatched. It's a pity to sit down at the front table in the middle of the night, not asking about the common people or the ghosts and gods. (Jia Sheng, Li Shangyin of the Tang Dynasty) Jia Yi in the Han Dynasty was a very talented politician who was once ostracized by ministers and exiled. The meaning of the first two sentences here is that Emperor Wen of the Han Dynasty summoned the exiled Jia Yi in the propaganda room. This was a very glorious thing in the eyes of feudal literati. This opportunity was a once-in-a-lifetime opportunity, implying that talents could be brought into play. The third sentence means that Emperor Wen of the Han Dynasty inquired humbly and listened attentively, making the two people very close. The fourth sentence laments that Emperor Wen of the Han Dynasty listened so intently. He was not asking about major events in the world, but about stories about illusory ghosts and gods. The third and fourth sentences were originally about Emperor Wen's love for talents. The poet used this article to reverse his intention, satirizing Emperor Wen for not really loving talents, and lamenting his lack of talent. The above examples 4 and 5 both quote the main idea of ??the original text and then raise objections, which fall into the third category of counter-use.

Introduction to borrowing:

There are two types of borrowing. One is also called "replacing", which means that the original meaning of the original text is neither the same, similar, nor opposite to the meaning to be expressed, but is only related in a certain aspect. It can innovate, enhance vividness, and produce humorous effects. It can also arouse readers' association with the story and enhance the image. Another method is to borrow symbols from mathematics and combine them into a simple formula to express complex ideological content, achieve the purpose of being concise and comprehensive, and have an intuitive and visual artistic effect. For example:

1. Those who want to achieve great things in ancient and modern times must pass through three realms: "Last night, the west wind withered the green trees, and I climbed up to the tall building alone, looking at the end of the world." This is the first realm. "The belt is getting wider and wider, but I don't regret it anymore. I feel haggard because of the loss of my clothes." This is the second state. "The crowd searched for him thousands of times, and when I turned around, I suddenly saw that man in a dimly lit place." This is the third realm. (Qing Dynasty Wang Guowei's "Human Words") "Last night, the west wind withered the green trees, and I went up to the tall building alone, looking at the end of the world." It comes from Yan Shu's "Butterfly Love Flower" in the Song Dynasty. The original meaning was to write in the desolate late autumn, to climb up to the tall building alone and look at it with regret. Here it is used Coming as the first realm means pursuing the ideal. "The belt is getting wider and you will never regret it, and you will feel haggard because of your love." It comes from Liu Yong's "Die Lian Hua" in the Song Dynasty. The original meaning is that one gradually becomes haggard because of missing one's lover, which expresses the pain of lovesickness. It is used here as the second scene. It means hard pursuit and exploration. "The public searched for him for thousands of times, but when he turned around, he suddenly saw that person in a dimly lit place" comes from Xin Qiji's "The Sapphire Case" of the Song Dynasty. It was originally intended to describe the surprise of accidentally discovering the person you like. It is used here as the third scene, which means success. , achieve the ideal joyful mood. These three quotations are all about the sorrow of separation. The author uses their correlation to compare the three realms of scholarship. He just extends the original meaning of the quotation to enhance the vividness of the article. There is no deep meaning and it is a borrowed technique. .

2. In the hot weather, the rich are still busy socializing and sweating profusely, but the poor take a shabby mat and spread it on the road, take off their clothes and bathe in the cool breeze. They have endless fun. This is called "sweeping the world" . (Lu Xun's "The Law of Peace and Poverty") "Sweeping the world" comes from Jia Yi's "Guo Qin Lun" of the Han Dynasty. The original meaning is that Qin Xiaogong wants to annex the world. It is deliberately misinterpreted here to misinterpret the meaning of the text, arouse readers' associations, and enhance the image of the article. It is used to It represents the scene of poor people rolling up their mats and sleeping on the open ground.

3. Xiao B: "Bubbles!" Mom: "Xiao Ji, hurry up and find a small basin!" Dad: "Wait, Xiao B, don't let it go yet!" Follow Xiao Ji's lead Walking, under the bed and under the chair, we split up to look for the small basin. I was so nervous that I kept shouting and walking: "Where is the small basin?" In this room, I don't know where to go. No matter what, I can't find the small basin. Mom dragged Xiao Yi as fast as the wind, and went to the toilet. The storm gradually subsided. (Lao She's "Literary By-Products") "Only in this house, the clouds are deep and I don't know where to go" comes from the poem "The Seeking Hermit Is Not Encountered" by Jia Dao of the Tang Dynasty: "Panasonic asked the boy, saying that the teacher went to collect medicine. Only in this mountain, the clouds are deep Don't know where to go.

"The author borrowed the last two sentences and changed the word "mountain" to "house" to describe the situation where the child wanted to pee and the whole family went out to find a urinal, but the urinal was missing. This is different from the original meaning of the poem. Or on the contrary, it is just because I don’t know where to find the urinal in the house and I don’t know where to find the master in the mountains. The scenery makes sense, so I quoted it. This enhances the humor of the article and makes the text more interesting. The above three examples all belong to the first method of borrowing, which is to use borrowing to enhance the vividness and image of the text and produce a humorous effect. p>

4. If you have to, I think it is better to bring some animality. It would not be very interesting if it conforms to the following formula: animal nature = a certain kind of person (Lu Xun's "A Brief Discussion on the Face of the Chinese"). Human plus domestic animal nature equals a certain kind of person. At first glance, we have never seen it and don’t know what theory or formula this is. In the author’s opinion, it is a “certain kind of person” with the docile character of a “domestic animal”. In fact, it is tantamount to eliminating the "animal nature" and losing the spirit of resistance. As the article says, it is "of no benefit" to him. It just makes "shepherds like it." The author borrowed the word from mathematics. The symbols " " and " = " make them form a complete addition algorithm, cleverly and clearly expressing his serious theme of resistance, because taming is of "no benefit" to us Chinese, it just makes foreigners People just like it. This kind of description is concise and concise.

5. The author believes that the mistake Hu Shi made was because he only paid attention to its indivisible side, so he concluded that stone = Jia Baoyu. =The conclusion of the author (Cao Xueqin) puts forward the autobiography (Ma Li's "Looking at the Role of "Stone" in "A Dream of Red Mansions" from the Narration Technique") Hu Shi once thought one-sidedly about the narrator (Stone) and the protagonist (Jia) of "A Dream of Red Mansions". Baoyu) and the author (Cao Xueqin) are actually the same person. In order to illustrate the point that "he only noticed its inseparable side", the author of this article borrowed two "=" signs to make Hu Shi's wrong view concise and clear. Expressed intuitively, it adds vividness and humor to the article.

6. Genius = 2 inspiration 98 sweat (Edison's famous saying) This sentence is a famous saying of the great American inventor Edison. We often use it today to prove that genius is not obtained by idleness. It is actually obtained by hard work and hard work. This formula vividly illustrates the dialectical relationship between genius, inspiration and diligence. The words are summarized, simple and clear, but comprehensive. The above three examples 4, 5, and 6 all use mathematical symbols to express certain intentions and certain thoughts and feelings. They are concise and concise, and can produce intuitive image artistic effects. The second method of borrowing.
