Introduction to Pipa Lake: Pipa Lake was built in 1972, also known as Yonghong Reservoir, which means a water conservancy facility built under the call of Chairman Mao to overhaul water conservancy. It was named because the lake surface resembles a Pipa and there are lifelike Pipa stones beside the lake. Pipa Lake is backed by a mountain facing the sun, with steep valleys and dense forests, forming a unique water scenery. It has complete tourist facilities and is the main gathering place for tourists on Chaya Mountain's "Canyon Boutique Tour Route".
