Introduction to Qiquan: The back door of Zhong'an Hall is an almost vertical cliff. The root of the cliff is a stone platform about 30 meters long and 5 meters wide. When you walk in, you can see two spring wells next to each other. , on the stone wall beside the spring is the word "Qiquan" written in cursive by Wang Tong, which is elegant and graceful. What seems to be two wells is actually one spring, connected to the left and right. The strange thing is that the first well is clear to the bottom, and the first well appears a little turbid. The second well has never dried up all the year round. Since ancient times, the holy spring has been famous far and wide, because it has the functions of strengthening the heart and spleen, preventing and curing diseases. It is said that the rich and wealthy people in Haizhou City used to drink from this spring even though they were hundreds of miles apart. Nowadays, Qiquan water is famous all over the world for its clear and sweet taste, which can quench thirst and promote body fluids. It has become a golden sign that Yilu people are proud of.
