Laozi. "A small victory depends on strength, a medium victory depends on wisdom, a great victory depends on morality, and a great victory depends on Tao". The whole sentence is that the small victory depends on strength, the middle victory depends on wisdom, the big victory depends on morality, and the big victory depends on Tao, which is the sum of morality, wisdom and strength. Laozi, also known as Tao Te Ching, is a pioneering work of Taoism and one of the basic classics of China's classical thoughts.
