Introduction to Wulong Biquan: Wulong Biquan is located in the upper part of Liucui Garden in the park. It is made of bluestone, 24 meters long and 3 meters high. Five flying dragons are carved on the wall with majestic heads and horns, which can be seen directly from the bluestone wall. When they come out, they open their teeth and dance their claws with a mighty attitude, and they spurt out hot springs straight into the clear pool, forming a three-dimensional picture of five dragons traveling in rain.
