What is Tai Chi?

The sun, the moon, the sun is very bright and hot, so it is called the sun. The brightness of the moon is too low for the sun to reach, so the ancients didn't invent a novel name for the moon.

In primitive society, the length of the sun shadow was measured by a vertical rod. Tai Chi map records the length of the sun shadow. Tai Chi? The so-called limit? The solstice in winter and the solstice in summer are two poles, that is to say, Tai Chi produces two kinds of instruments.

Tai Chi gives birth to two devices, day and night. Warm season? Cold season,

Two instruments give birth to four elephants, early noon and late midnight, spring, summer, autumn and winter.

The system of the Huang family originated from the primitive society in the Central Plains, and its concern is the summary and induction of human animal instinct and the natural laws of all things in the universe.

The laws of astronomical climate are very important in Huangdi's Neijing.
