Introduction to Qunying Lake Dam: Towering in the "Narrow Mountain" canyon, it was built in 1971. The dam is 100.5 meters high and is the tallest masonry arch dam in China. The entire dam is majestic and has smooth lines, like a giant dragon lying down. The waterfall on the top of the dam is like white water splashing down, hitting the rocks and hitting the shore. The mist is like a rainbow in the sky, which is magical and spectacular.
