Introduction to Upper Pool and Lower Pool: It is said that in the early years, a gardener grew flowers for Grandma Taishan on Huapo. When Grandma Taishan came to enjoy the flowers, she heard that there was insufficient water, so she pointed her fingers and formed two pools near Huapo - —Upper Pool and Lower Pool. Among them, Shangchi is located 2 kilometers east of Zhongjun Zhang, north of the main highway, and not far to the north is Xiachi.
