What is a red, black and white triad?

This theory is a further development of Zou Yan's theory of five virtues rotation in the Eastern Zhou Dynasty.

The order of five virtues is civil, gold, fire and water, and the replacement of dynasties follows this order: soil (yellow emperor, etc. ), wood (summer), gold (business), fire (week), water (Qin) and earth (Han). ......

This theory holds that countries and things are constantly changing, and at the same time, major changes in national politics are often related to changes in astronomical phenomena and natural things, which can be regarded as the pioneer of Dong Zhongshu's theory of heaven-man induction.

Looking at the development of Dong Zhongshu again, Dong Zhongshu believes that the change of dynasties is not only related to the five virtues, but also follows the three systems of black, white and red. Each dynasty follows the great unity and each system has its own governance style. Later generations explained that the black system advocates severe punishment and strict laws, the white system advocates the worship of ghosts and gods, and the red system advocates human etiquette. However, in Dong's theory, there is no difference between these three systems. He emphasized that the establishment of a dynasty is due to the fate of heaven, and it is based on the reincarnation of three systems. To change the dynasty, it is necessary to change the name of the country and take the color era, which shows that he is the new Mr. Right. This theory also declares that a dynasty cannot expect to rule forever, which is also a warning to the rulers.

To put it bluntly, the so-called three-in-one rotation is to change the national symbol, just like changing the sky and sky into five-star red flags when New China was founded.
