General knowledge is an important concept in China's ancient Confucianism. It comes from the statement in Eight Items of the Book of Rites-General knowledge, honesty, self-cultivation, keeping the family in order, governing the country and leveling the world. Knowledge exists in things. The content is known, and the knowledge is sincere. However, this passage is the only passage in Da Xue, but no explanation was given afterwards, and the words "Wu Ge" and "Zhi Zhi" were not quoted in ancient books in the pre-Qin period, which made the true meaning of "Wu Ge Zhi Zhi" a mystery of Confucianism. The fifth edition of Modern Chinese Dictionary published in 2005 interprets "knowing knowledge by studying things" as "reasoning about the principles and laws of things and summarizing them as rational knowledge".
