1. The Jinkou River Grand Canyon has been there several times. The first few times were from the Jinkou River. This time, we went back from Hanyuan. The road was very flat and easy to walk. The car with a lower chassis had no problem. The scenery along the Dadu River was very beautiful. Because it was rainy season, there were rubbles falling from the mountains on some roads. 2. There are no tickets for the Grand Canyon. There are signs at both the beginning and the end of the Grand Canyon. From the Jinkou River into the canyon to the Hanyuan direction, through the tunnel, it stops at the Shenxigou Bridge. Located in the traffic lane, there are not many traffic, there are two or three viewing stations along the way, and there are not many places to take pictures, and the effect of the pictures is very limited by the weather. In fact, the scenery is very beautiful. Just feel it with your heart. Along the way, many large hydropower stations have been built, and the water flow has been much smoother. 3. There is the Railway Soldier Museum, Dongzhong Railway Station, which is the only Dongzhong Railway Station connected by bridges and tunnels in China. It is worth visiting. 4. Non-open area. Foreigners are not allowed to enter without permission. It is said that this area is the only area that foreigners are not allowed to enter in Sichuan or in China (without official reports). It has been rated as one of the ten most beautiful canyons in China. East of the Usi River to the Jinkou River, it is 26 kilometers long, less than 200 meters wide, but the depth of the valley is 2600 meters. Along the river, there are Jinwu Highway and Chengdu-Kunming Railway running side by side. On the mountain, there are Lexi Highway built during World War II, circling in all kinds of dangerous situations. Jiangshan ink painting, fresh and elegant, like the shallow time, why not allow me a sunny day?
