The main project of Dujiangyan Canal Head is mainly composed of three main projects: Yuzui, Feishayu and Baopingkou. The three organic cooperation, mutual restriction, coordinated operation, water irrigation and irrigation, flood diversion and mitigation, so the first thing you see when entering the scenic spot is the Baopingkou water diversion project. The bottle mouth acts as a "control gate", which can automatically control the water intake of the inner river. It is an opening cut on the long ridge of the Lijiang River (now the name Guankou Mountain and Yulei Mountain). It is artificially chiselled into the throat of the inner river to control the water intake. It is shaped like a bottle mouth and has a strange function. The hill on the right side of the bottle is called off the pile because it is separated from the mountain. Dujiangyan is the only dam-free water conservancy project in the world that is still in use. Now it is showing a variety of deeply nostalgic beauty while playing a huge water conservancy utility. Recommended tour route: Dujiangyan Scenic Area is away from the Duimen → Wotie Square → Qingxi Garden → Fulongguan → Baopingkou → Feisha → Fish mouth → Anlan Bridge, and then go to the scenic spots such as Yugongtang, Erwang Temple, Songmao Ancient Road, Yuleiguan, Mawang Palace, Chenghuang Temple and other attractions. The whole tour takes about six hours. Tickets for Dujiangyan Scenic Area are 80 yuan. Tickets for on-site purchases and online reservations are all swiped ID cards to enter. There is no paper ticket to be taken. You can play according to the attractions on the ticket. The whole scenic area is mostly humanistic. I personally think that I should do my homework or listen to the tour guide first. Listen to the explanation to experience the grandeur and wisdom of Dujiangyan. Don't enter the scenic spot and walk along the river from the South Bridge to see the bottle mouth. I am clockwise, an older youth who loves travel, photography and punching in.
