It is a famous saying of Han Yu, which means that the depth of learning lies in diligence, while negligence lies in fun. This sentence comes from Han Yu's interpretation of learning. It tells us that the key to a person's knowledge and conduct lies in diligence or pleasure, in thinking or following; If you want to make progress and success in your studies, you must be diligent and thoughtful. It applies to all people at all times and in all countries. Regarding diligence, Modern Chinese Dictionary is interpreted as "doing as much as possible or persisting in doing (as opposed to being lazy or lazy)" and so on. Etymology is interpreted as "diligence, hard work, kindness, helping others" and so on. The word "diligence" can be seen everywhere in idioms and cautionary sayings of past dynasties, such as: diligence can make up for mistakes, diligence is good at asking questions, diligence is hard to practice, and diligence is not lacking; "Hard study is expensive, and the meaning of the text must be high"; "Wisdom comes from diligence, and greatness comes from the ordinary"; "knowledge is boundless, you must study hard, youth is limited, but you cherish yin"; "A skill should start with diligence, and teenagers should not stay for teenagers"; "There is a road in Shushan, and it is difficult to learn from the sea." "A year's plan lies in spring, a day's plan lies in morning, and a lifetime's plan lies in diligence"; And so on. These famous aphorisms are all explaining a truth. Ancient and modern "knowledgeable person" can achieve great success without diligence, which is the evidence that "diligence is better than diligence". Around us, the success achieved by hard work can be seen everywhere. Here is another small example around me. About 20 years ago, I personally participated in the arrangement of two single veterans, yum and yaom. With the help of the government, family life is also very happy, and children have also gone to college. However, yaom chose a different attitude towards life from yum. The government helped him find a job several times, but he was very picky and gave up. So far, he has been sleeping on the street. We can only live on subsistence allowances. The former is diligent, while the latter is playful. Different attitudes towards life lead to different life outcomes. There is Yan Ruyu in diligence, and there is a golden house in diligence. Hard work and playful life choices are inseparable from thinking. Thinking, modern Chinese dictionary. It also means self-reflection. If you want to succeed in life, you should think twice before you act. The process of thinking is also a process of learning, investigation, analysis and choice. Every step of the way, people should think carefully and make choices, and they should not go with the flow. "You can't make a leap in ten steps, but you can't succeed."
Industry is diligent and lazy, which comes from Han Yu's "Persuading Learning". It means that learning is proficient because of diligence, but it is abandoned in laughter. Things succeed because of repeated thinking, but they can also be destroyed casually. Throughout the ages, many people who have achieved their careers have come out of diligence and laziness. There is a good allusion that is also true.
During the Warring States Period, Su Qin was ambitious at first, but because of his shallow knowledge, he was not reused in many places. Later, he made up his mind to study hard and sometimes read until late at night. When he was really tired and ready to take a nap, he stabbed his thigh with an awl, which made him bleed profusely. He used this special "stabbing" method to drive away drowsiness, cheer up and keep studying. Later, he finally became a famous politician.
