Located at the north end of Baishou Town, Yongfu County, Guilin, the ancient town of Yongningzhou is surrounded by mountains and rivers, with beautiful scenery and a feng shui room. The first thing I saw was the "South Gate", which is the only heavy-lift mountain-top-style building in the four gate buildings in the east, south, west and north. The others are single-window buildings. The city gate made of blue stone is written in three big words "Yongzhenmen". After reading the introduction on the stone carvings by the door, I found that this should have been called "Zhenningmen". It is unknown why the name is changed. On a whim, I stepped on the overgrown stone ladder on the left and climbed the city gate. The sky is far away, the blue and gray city walls under the sky are stretched westward, the houses in the city are shadowed, the blue bricks and black tiles, and the moths are arched. The sky is a bit cloudy, the clouds are thousands of miles, the wind is very strong, and the wind stands, which is inevitably floating.
