Fu's ancient "gossip" began with observation. After observing heaven, earth, people and things in general, he summed up the results and made them into the ideological symbols of gossip. This is the procedure of philosophical thinking. Starting from the natural phenomena in front of us, through observation, synthesis and comparison, we can get the commonness of all things, and then summarize and create image figures to represent this commonness. The first sentence of this passage says that gossip is produced by summing up the commonness of all things, so it can "communicate" the virtues of all things ("virtue" is virtue); The latter sentence is characterized by universality, so it can be divided into eight categories according to the actual situation of everything (referring to eight kinds of gossip, such as heaven, earth, thunder, wind, water, fire, mountains and rivers).
What is Yi? First, change, everything in the world is changing all the time. Heaven and earth run, cold and summer alternate, mankind dies, and there is no time. Second, simple, one yin and one yang, all-encompassing. Every day, there are land, men and women, ups and downs, and before and after, all of which are complementary and unified. Third, it is not easy. Although things in the world are complicated and changeable, one thing will never change, and which one will not? The law remains unchanged. A month's profit is a loss, a day's noon is a deviation, and things will turn around. This is the law of all things. Who can escape this rule? Unless you jump out of the three realms, you are not a fairy in the five elements. After thousands of years of living practice, the Book of Changes contains profound natural laws and simple harmonious dialectical thoughts.
