Diligence is diligence, which means that academic progress lies in diligence. People's behavior can only be realized by thinking, but it disappears in laziness, rashness and informality. Tang Hanyu's "Learning and Knowing": "Industry is good at diligence, and play is not hairy; Everything I have done is thought and destruction. " Xin Li's "cliche": "As the old saying goes,' diligence is good at diligence' ... a word' diligence' tells the mystery of mastering business technology."

The word comes from Han Yu's Jin Xuejie, and the original text is as follows:

Diligence is good at diligence, barren is good at playing; What I did was thought, but it was destroyed. When the sages meet today, the fixed object has been finished, the evil spirits have been pulled out, and the good spirits have been worshipped. Small and good are recorded, and the famous ones are useless. Guy was lucky to be elected, but there were more clouds than many. Not all students are proficient, and there is no ignorance of the department; You can't succeed if you suffer, and you can't suffer if you suffer.

It means:

Academic progress comes from diligence, and waste comes from vagrancy and play; Success in doing things for people comes from thinking, and corruption comes from following the rules. At present, when a saint meets a saint, everything follows the law. Get rid of the bad guys and choose people who respect them. Those who have a little strength have been accepted, and those who are famous in technology have been appointed. Collect talents, screen, educate, cultivate, scrape off their dirt and temper their light. Probably only those lucky enough to be selected, who said that they are versatile and not honorable? You students are only worried that you can't make progress in your studies, and you are not worried that the officials in charge of the department are not accurate; I am only worried about the inaction of ordinary people, and I am not worried about the unfairness of the officials in charge.
