[Mid-Autumn Self-driving Nine Gates Water Great Wall] I took my mooncakes from Dalian, sat on the high-speed rail and joined my parents, and drove the Mid-Autumn Festival holiday together. After the autumn rain, I came to the Great Wall on the water in Jiumenkou! Located on the outskirts of Yuzhong County, the Great Wall of Jiumenkou Water is located at the junction of Liaoning and Hebei provinces. It was built in Beiqi and expanded in the early Ming Dynasty (1381). It is connected to the Great Wall in the direction of the Southern Shanhaiguan, and has been extending northward to the Jiujiang River, and then built a huge spanning river bridge over a hundred meters, named after the city's nine diarrhea gates.
