Why did people in China's "Yellow River Floods" become geographically discriminated in history?

Cheaters in Henan, beggars in Anhui, coolies in northern Jiangsu and robbers in Shandong are the most popular people at the bottom of the chain of regional discrimination in modern China.

Although such accusations can't stand scrutiny.

For example, there are many swindlers in Henan, but the well-known fraud crimes in the past decade have nothing to do with Henan.

Coincidentally, these four places that cause regional discrimination, namely eastern Henan, northern Anhui, northern Jiangsu and southwestern Shandong, are not only geographically adjacent, but also belong to the lower reaches of the Yellow River.

As it happens, it coincides with the "Yellow Pan Area" that the US Mission recently despised.

Many times we refer to the "Yellow River Flooding Area", which refers to the area around Henan, Anhui and Jiangsu where the Huayuankou section of the Yellow River was blasted, causing serious floods.

But in fact, the "Yellow River flood area" has existed since ancient times, and it was named after the flood when the Yellow River burst its banks. In the history of China, he was an absolute protagonist, suffering and pain, bloody revolution and even regime change.

If there had been regional discrimination at that time, people in the "Yellow River Pan-area" would have stood at the top of the discrimination chain.
