Introduction to Fengshan Water Plant: There is a spring in Fengshan with a sweet taste. It is located behind the reservoir of Fengshan Water Plant and is as big as a ballpoint pen. It turned out that people visiting Fengshan Park forgot to bring water, so they dug a small well at the spring and filled it with leaves to quench their thirst. Next to the spring is a southwest birch tree with a unique shape. It is divided into several branches from the root and curves upward, covering a certain amount of the ground. It is surrounded by artificial fir, cherry and secondary shrubs. It is in a shady place and is exposed to sunlight. It is difficult to directly shine into the spring, so in the hot summer, it is very comfortable and pleasant to drink the clear spring here to quench your thirst.
