Introduction to Liupanguan Village: Liupanguan Village is located on Liupan Mountain, 20 miles east of Longde County. During the Eastern Han Dynasty, Niuhandhai Wating relied on Liupanguan Village as a barrier. During the Tang Dynasty, Liupan Pass was set up here, which was one of the seven passes in Yuanzhou. It was the so-called "strangling the throat of Jiuzhaigou and the lapel belt of seven passes".
