In the northeast corner of today's yancheng middle school campus. The water in the well is deep and sweet and has been preserved for nearly two thousand years. In 6 16 AD, the leader of the peasant uprising was Wei Che. According to Yancheng, he was the king and built a palace outside the south gate of the county seat. Hanging in Beijing became a part of the royal garden. Later, Emperor Taizong Li Shimin surrendered to Wei Che. In order to destroy the feng shui of this "land of real dragons", Wei Che's palace was demolished, and a Yongning Temple (Yongning Temple has a long history) was built next to Guajing, which became a drinking well for monks in the temple. After Emperor Taizong unified the world, he restored Yancheng's tucheng. Tucheng was built four times in Song and Yuan Dynasties. It was not until the 16th year of Yongle in the Ming Dynasty (AD 14 18) that the county moved to the southwest, and the tucheng was changed into a brick city. At this time, Guajing was surrounded by the east gate of the county. So now the location of Salt Lake should be the location of Yancheng Ancient City Wall: Yingbin Road outside the East Gate of Salt Lake. This used to be a river decades ago. When it was a moat, Jiefang Road outside the west gate of Salt Lake used to be a small road, which was called "City Wall Road".
The story of Hanging Mirror Fairy Tale probably comes from Gao Cen's poem Hanging Mirror Fairy Tale in Qing Dynasty:
From his famous place, the same east gate as Sun Gong's former site is respected.
The complete path of spring is not mature, but the Ludan people still exist when they reach the well.
There is no ancient day in the sea and the sky, but there are descendants in the Han Dynasty.
Where to listen to the misty fairy tale, it teaches people to stop at the ecstasy of darkness.
It is also said that there are immortals here (it is unknown whether they are foxes or Wong Tai Sin), so they were very popular with literati in the Qing Dynasty and were promoted to one of the "Eight Scenes of Yancheng".
