Reading can be used as a pastime, as a decoration, and can also increase one's talents. Reading can be a pastime when you are lonely. When you speak, knowledge can be modified. When doing things, knowledge is talent. Those who know the cause and effect of things are lucky. Although people with practical experience can handle individual affairs, only knowledge can do it if they want to look at the whole and plan the overall situation. People who study too slowly are lazy, reading for decoration is deceptive, and people who follow the book completely are fools. Knowledge can improve human nature and experience can improve knowledge itself. Human nature is like wild flowers and weeds, and learning is like pruning and transplanting. Although knowledge can guide the direction, it is often superficial and must be based on experience. Cunning people despise learning, fools envy learning, and wise people use learning. Knowledge itself does not tell people how to use it, and the wisdom of using it lies outside books. This is a skill that you can't learn without experience. The purpose of reading is to understand the principle of things. Studying for critical arguments is boring. But don't be too superstitious about books. The purpose of seeking knowledge is not to brag or show off, but to seek truth and enlighten wisdom. Books are like food. Some need to be tasted, some can be swallowed, and only a few need to be chewed carefully and tasted slowly. Therefore, some books only need to read part of them, some books only need to know the outline, and for a few good books, we should read them thoroughly, carefully and repeatedly. Some books can be read by someone instead and then read the summary of his notes. But this should be limited to unimportant reviews and books of poor quality. Otherwise, a book will be as tasteless as distilled water. Reading makes a full man, discussion a ready man, and writing an exact man. Therefore, if someone doesn't study and wants to pretend to be knowledgeable, he must be very cunning and hide his eyes and ears. If a person is lazy in writing, his memory must be strong and reliable. If a person wants to explore alone, his mind must be extremely sharp. Reading history makes people wise, reading poetry makes people wise, learning mathematics makes people precise, physics makes people deep, ethics makes people noble, logic and rhetoric make people able to contend. In short, "knowledge can shape a person's character". Moreover, all kinds of mental defects can be improved by seeking knowledge-just as physical defects can be improved by proper exercise. For example, playing ball is good for the back, archery can expand the chest and moisten the lungs, walking can help digestion, riding a horse can make people react quickly and so on. Similarly, an inattentive person can also study math, because math will make mistakes if he is not careful. People who lack analysis and judgment can study and go to school, because this subject pays the most attention to trivial dialectics. People who are not good at reasoning can study legal cases. And so on. This mental defect can be improved through study. Today's responsibility lies not with others, but with my youth. Teenagers are smart, rich, strong, independent, free and progressive, better than Europe and better than the earth. The red sun rises, and its road is bright; When a river comes down, it pours into Wang Yang. Dive into the depths of the dragon, scales flying; The milk tiger roars in the valley, and all the animals are surprised. Falcon wings, dust suction; Strange flowers are born, and they are called emperors. Dry hands can make a difference, but they can also make a difference. The sky wears its gray and the earth wears its yellow. Even if there were years, there were eight famines. The future is like the sea, and there is plenty of time. Beautiful, I am a young China person, and I am not old; Zhuang Zi, China teenager, borderless! "
