Introduction to Butterfly Valley: Butterfly Valley is one of the four major scenic spots in Dinghu Mountain. It is composed of three parts: green lake, small island and forest. It is a paradise that integrates sightseeing, butterfly appreciation, tea tasting and adventure. To enter the Butterfly Valley, a cruise ship is the only means of transportation. Boating on Ding Lake, cutting through the clear green lake, and listening carefully, the sound of boating and the chirping of birds and insects "sing together" are very interesting.
