The Picyun Building is the core attraction of the ancient city wall scenic spot. In the past few years, tickets have to be allowed to climb the building. Now in order to develop the ancient city to attract more tourists, it is now free to climb the building. Although the existing building is a rebuilt building, it is still very worth a visit. The whole ancient city wall and Zhaoqing City can be seen on the building, and there is a historical introduction of the transformation of the ancient city in the building, which is very knowledge-raising.
