What exactly does "Richen" in "Six Benevolence" mean?

If six Sai Ren enter, tomorrow will be the first day. "This sentence points out the key to the study of Liu Ren, and clearly puts forward the importance of Li Chen. We have no way to prove what the Japanese and Japanese originally meant in this sentence. According to the explanation in the market, we think it is the daily line of the day.

Chen is a first-class Chinese character, pronounced chén, which was first seen in Oracle Bone Inscriptions. Its original meaning refers to the stinger after waking up from fright, which is extended to vibration (that is, the so-called "shock" in Shuo Wen Jie Zi), and also refers to the floorboard of the sun, the moon and the stars. It can refer to Beichen and the stars in general, the heart of one of the 28 nights in general, and the sun and the moon in general.

The starting point of the interpretation of the six benevolent people is that the moon will turn out of the world together, that is, the infinite gives birth to Tai Chi; Heaven moves to produce yang, while earth is still to produce yin, that is, Tai Chi produces two instruments.

By the day, four lessons are discharged, that is, two instruments and four images; There are three biographies from the nine clans, that is, four elephants give birth to gossip.

This is the simulation process of "Tai Chi gives birth to two instruments, two instruments give birth to four images, and four images give birth to eight diagrams" in the Book of Changes.
