The tourist attractions in Tongguan are as follows: 1. Dongmen Tower faces the Yellow River in the north, the Qilin Mountain Corner and Yuanwanggou Graben in the east. It is the only way to enter the customs from the east, which is extremely dangerous and has the trend of "one guard, ten thousand people can't force". 2. There are no ditches and dragons. The blue waves are rippling, the fish are jumping and making waves, the trees are shaded, the flowers are fragrant and the birds are singing, which has the charm of Jiangnan water town. 3. The silver in the snow case is a tree, the jade is a peak, and the powder plastic railing is wrapped in mountains and rivers. If it is sunny after snow, it is silver, Qiong Yao is pale, and the viewer is in a trance in fairyland. 4. Wind chimes and small bellies look up and down at the Yellow River, with endless smoke and flashing masthead lights. Ships galloped in the north and south, colorful sails fluttered in the east and west, and the wonderful symphony that crossed in the morning echoed on both sides of Gudu. Where is Tongguan?
