Gongchen Building is the north gate of the ancient city of Lushan, which has a history of more than 600 years. It was originally a three-story building, and it was changed to a two-story city building after more than 200 years of use. The front is hung with a plaque of "Ten Miles to Look at the sky", but the "Kuixiong Six-Square" hanging behind is more powerful, symbolizing the glorious history of the unification of the six-square kings in the south. The side of the city building is also very beautiful, from time to time there are tourists wearing Bai costumes in this travel photography, the surrounding streets are clean and open, the shops are orderly.
