Unlike other ancient cities in China, there is not much commercialization in the ancient city of Langzhong. Many shops here are run by local people. There is no such thing as a bar street, and there are no shops selling souvenirs everywhere. The green leaves make the trails cool, and the lanterns under the eaves are already yellowed. The tourists walking on the road stop and go, occasionally. I heard some mahjong sounds in the old house. When you feel the time here, slow down and discover the beauty of its architecture. The ancient city stands in the middle of the mountain ring, and its architectural layout also strictly follows the layout of Feng Shui, reflecting the concept of Feng Shui in ancient China. The tallest building in the entire ancient city is the Zhongtian Building. It was built in the three-storey high-rise building of the Ming and Qing Dynasties in the Tang Dynasty. Looking into the past, you can see that there are different plaques in the direction of the four sides of the attic. The surrounding streets are centered on it.
