When Li Zicheng opened the seal, he also crossed the Yellow River embankment, but the impact was not as great as this time. It coincided with the rainy season, and there were overlapping flood peaks. The water was already heavy, and the remote location was at a key location on the Yellow River. Copper

The Yellow River here in Washiang turned a big bend and flowed southeast. This breach spread to the northeast, and most of Shandong was affected.

Li Zicheng opened Kaifeng three times and broke open the embankment of the Yellow River. The water rushed into Kaifeng. It is said that the 340,000 people in the city were almost killed, and only about 30,000 people remained.

This breach will surely cause disasters to tens of millions of people.

In fact, the previous course of the Yellow River was also artificially diverted. In order to prevent the Jin soldiers from going south, the Southern Song Dynasty army dug up the Yellow River embankment in Huaxian County, Henan Province and blocked the soldiers with water, causing the Yellow River to flow into the Surabaya River and finally seize the Huai River and flow into the sea.

After this time, the Yellow River formed two river channels, the old and the new, and swayed everywhere from the Yellow River to the Huaihe River. Since this location happened to be on the front line of the confrontation between the Southern Song Dynasty and the Jin Dynasty, neither the Song Dynasty nor the Jin Dynasty had any intention to block the breach, so that the Yellow River was in

Throughout the Southern Song Dynasty, there was a situation of overflowing and oscillating conditions in the north.

Later, the Jin Dynasty was defeated by the Mongols. Pursued by the Mongols, Jin Aizong had to flee south to Kaifeng, and then fled to Guide, which was only more than 200 miles away from Kaifeng. At that time, the Jin soldiers tried to open up the water of the Yellow River.

Flooded the Mongolian army, but all the troops sent out to dig up the embankment were wiped out. Then, the Mongolian army did not stop, and a general came up with a plan to flood Guide, so they directly dug up the embankment of the Yellow River. Unexpectedly, the terrain of Guide City was high

, the water of the Yellow River actually flowed around the city, but the overflowing Yellow River caused great harm to the Yellow Flood Area.

Two years after the Mongols opened up the Yellow River, taking advantage of the peril of the Jin Dynasty, the Southern Song Dynasty army went north to compete with the Mongols for the Central Plains. In order to stop the Song Dynasty army, the Mongols again artificially opened up the Yellow River. This time, the location was chosen just over 20 meters north of Kaifeng City.

This also caused the fifth major diversion of the Yellow River in history.

No one could have imagined that now that the Ming and Qing Dynasties were fighting in the Central Plains, the local Tatar governors, fearful of the rebels who would defect to the Ming Dynasty, also came to block the troops by digging up dikes and releasing water, which would cause the sixth major diversion of the route.

Gao Yuanmei and others would not have thought that although they had protected Caozhou Mansion from being captured by the rebels, and even severely damaged Li Huajing's rebels, this move was tantamount to a stab in the heart of the Qing court.

The Qing government, which was originally very passive in the war in the Central Plains, lost Jiangnan, corrupted Huguang, and abandoned Huainan. Now Shandong has been flooded again. More than ten prefectures and forty prefectures and counties in three provinces have been affected, and seven or eight cities have been flooded and destroyed.

The yellow flood zone is one to two hundred miles wide and several hundred miles long.

The canals in Henan were washed away, and tens of millions of people were affected.

Isn't this a knife in the heart?
