"Square" and "circle" are two corresponding images with profound philosophical connotations in China traditional culture: square is rigid, circle is soft; Square is principle, circle is machine change; Square is the foundation of being a man, and circle is the way of life. The combination of square and circle, the combination of rigidity and softness, the coexistence of yin and yang, and endless changes, could be constant and changeable. It contains the essence of human wisdom, condenses the essence of life skills, and has been regarded as the avenue of life, the great wisdom of being a human being and the big end of doing things since ancient times. In being a person and doing things, if you could achieve a square outside the circle, a square inside the circle, achieve the unity of square and circle, we will be able to advance and retreat freely, be comfortable, deal with things calmly, turn crises into invisibility, and win a broad living space.
