Huangsiqiao Ancient City. The ancient city of Huangsiqiao, built in 686 AD, is the rule of Xiangyang County in the Tang Dynasty. The ancient city walls of height 5.6 meters, thick 2.9 meters, and circumference 686 meters are all built with glaucous stones. This city is a former earth city, which has been renovated and repaired over the past generations, forming a unique stone city. Miao family members living in and outside the ancient city still retain the customs of their ancestors. But few tourists here, climb the city tower, look around the city wall, the city wall has not seen the past bustling, left only dilapidated and messy, it seems to be waiting for the renovation and repair again.

At the Phoenix Hotel, you can take a direct bus, the fare is eight yuan, it takes one hour. After getting off the bus, walk for ten minutes. There is no charge from the west gate. The north gate needs 20 yuan management fee. There are three existing gate buildings. It is a very quiet small village. As a tourist area, the scenery is almost the same.

The scale is small, in disrepair for a long time, no one manages, an old man living nearby and an old woman forced to charge ten yuan per person at the door, it is not recommended to go.

It is the best preserved castle in China so far. It is the head of the ancient city. It is very beautiful. It is a thousand miles of good fields and green water.
