The famous sayings about principles are as follows:

1. "Mencius Li Lou Shang" written by Meng Ke during the Warring States Period: "The wisdom of Li Lou is the cleverness of the public and the son. Without rules, it cannot be square and round." ”

Explanation: With Li Lou’s shrewd eye and Gongshu Bang’s skillful craftsmanship, it would be impossible to draw a square circle without following rules and regulations.

It means that there must be rules and behavior systems when doing anything. The system is the rules and codes of conduct for everyone to abide by. No matter how complex things are, they can be explained with simple examples.

2. "Huainanzi" by Liu An of the Western Han Dynasty: If the moment is not correct, it cannot be square; if the gauge is not correct, it cannot be round.

Definition: The tools are placed incorrectly and the correct beginning cannot be drawn.

You must persevere in everything you do, regard "obeying disciplines and observing rules" as a kind of responsibility, establish a sense of discipline and rules, and fully realize the importance of observing disciplines and observing rules, and effectively strengthen the discipline and rules. Discipline means conscious thought and action.
