Who is the sage of the Yellow River talking about?

"Sages come out, Huang Heqing" comes from Deng Ji in Ming Dynasty: "Youxue Qionglin" means that the water of the Yellow River is turbid all the year round, and if it becomes clear, it is regarded as an auspicious sign. It is also a metaphor for rare and rare things.

"Sages go out of Huang Heqing" is an old proverb, which represents China people's attention and reverence for the Yellow River culture, and also shows the splendor and richness of China's ancient civilization.

This proverb means that when the Yellow River is clear, there must be saints. The "sage" here refers to a great man with great respect and outstanding talent. These people will promote social progress and development with their wisdom and contribution.

In the history of China, the Yellow River has always been an important symbol of Chinese civilization and a place of soul. The Yellow River Basin is one of the oldest cradles of civilization in China and an important center of ancient culture in China. The hydrological conditions of the Yellow River have an important influence on the development of agriculture, transportation and industry in China. Therefore, it is very important for the people of China to protect the water quality and basin environment of the Yellow River.

Scientific investigation

After modern scientific investigation, it is accurately known that the middle and lower reaches of the 5464-kilometer-long Yellow River are muddy water, and the upper reaches of the Yellow River, which accounts for more than half of the total length, that is, the area from Heyuan to Hekou Town, are clear. (People's Republic of China (PRC) and Ministry of Water Resources: China River Sediment Bulletin, 2000).

In the middle and lower reaches of the Yellow River, the river has also become clear in a short time, that is, the auspicious "clear river" recorded in history books is not only once every 500 years or even 1000 years.

According to the geological history expert Mr. Li Erong's textual research, there are 43 "Heqing" recorded in the history of China, which were first seen in the eighth year of Yan Xi (165). If you count from this time, it will be less than once every 40 years on average. (Li Erong: The Formation of the Hanging River in the Lower Yellow River; Talking about the Yellow River.
