The ancient city of Yazhou is the current Yacheng Town of Sanya City, which is the seat of Yazhou County in the past dynasties. Today, there are not many complete monuments left here. Yazhou Academy is one of the representative ones. It used to be a higher institution in ancient Yazhou. Both the buildings and the preserved antiquities are worth savoring. The ancient city of Yazhou is the southern wasteland where emperors exiled their rebels after the Tang Dynasty, leaving behind many well-known poems and stories. In addition to the relatively well-preserved Yazhou Academy, the existing monuments also include the newly renovated south gate "Civilization Gate" and the north gate "Ningxiu Gate" terraces, as well as some remnants of the city wall and the remnants of the moat and moat. Compared with the urban area of Sanya, there are not many tourists in the ancient city of Yazhou, and the locals are also very friendly. It is very pleasant to walk around here. There are also local specialty snacks in the ancient city, such as double skin milk and coconut milk, which taste authentic.
