1. Square is the rule, the framework, and the foundation of life; round is harmony, sophistication, and the way to live in the world. If there is no square, the world will have no rules and there will be no restraints; if there is no roundness, the world will be too loaded and it will not be able to take care of itself. When dealing with people, be square when you should be square, and be round when you should be round. There is a circle outside the square, and there is a square within the circle. Only when the square and the circle complement each other can society be harmonious. People often say that "there are no rules without rules" and "you can only do something if you don't do something", which is the principle of "square". That is to say, as an official, you must abide by the principle of integrity. In business, one must be sincere. Doing knowledge and belief is a "real" word.

2. "The Way of the Square" is a philosophical and inspirational book written by Chen Shukai. Focusing on the square, which is the foundation of one's life, and the circle, which represents the way of life, this book collects and organizes remarks about the way of life and life from a large number of typical classics, translates them into modern vernacular forms, and analyzes and comments on them.
