Who knows the origin of Hongze Lake?

Hongze Lake was called "Broken Kettle Pond" in ancient times. In the 12th year of the Great Cause of Sui Dynasty (AD 6 16), Emperor Yangdi of Sui Dynasty took a dragon boat from Luoyang to Jiangdu, and it was dry all the way. When he passed the "broken kettle pond", he was so happy that it rained heavily and the water level rose as far as the eye could see. On a whim, he changed the broken kettle pond to Hongzepu, hence the name Hongze. In the Tang Dynasty, it was renamed Hongze Lake.

Hongze Lake is located in the lower reaches of Huaihe River in the west of Jiangsu Province, on the west side of the central part of Subei Plain, in Huai 'an and Suqian, with a geographical location of 33? 06′—33? 40', east longitude 1 18? 10′— 1 18? 52' is the junction of the middle and lower reaches of the Huaihe River.

Originally a shallow lake group, it was called Fuling Lake in ancient times. After the Han Dynasty, it was called Broken Kettle Pond, which was called Hongzepu in Sui Dynasty and Hongzehu in Tang Dynasty. After 1 128, the Yellow River south migrated through Surabaya to seize the lower reaches of the Huaihe River and enter the waters below Huaiyin. The Huaihe River lost its access to the sea and stored water in the east of Xuyi, and the original small lake was expanded into Hongze Lake.

Extended data;

Hongze people regard "nine cows, two tigers and one chicken" as the "patron saint". It is said that the early Hongze Lake was still a calm lake. One year, a demon dragon came to Hongze Lake, and since then, Hongze Lake and Daqingshan Lake have lost their peace.

This demon dragon is a cloud in the sky. Suddenly, it enters the water as fog, lifts the lake, capsizes the boat, breaks the fishing net, and occasionally goes to Daqingshan to do evil, which makes fishermen and people on the lake panic and complain, and it is restless day and night.

So I immediately called the Jade Emperor and sent two tigers and 10 buffalo. After being defeated, the demon dragon fled into the underwater dragon palace. Later, the jade emperor sent a rooster to stick to his post and wake up the iron cow and tiger at any time. Later, I rode a green cow to heaven, leaving "a chicken"

Of course, legends belong to legends. For Hongze Lake, Bian Xiao also popularized it for everyone. According to historical records, Hongze Lake did not exist before the Tang and Song Dynasties, and some smaller lakes and swamps were widely distributed here. For hundreds of years, large and small lakes and depressions on both sides of the lower Huaihe River, such as Fuling Lake and Pofutang, have joined together and gradually merged into lakes, hence the name Hongze Lake.
