It starts from the southeast of Zhuizishan Hill to Jinniudong Cave, with the total length of 13 kilometers. The Great Wall was built with stone slabs, and bricks outside. It is 5 meters wide and 10 meters high. There are crenellations or battlements along the outer crest of the city wall and parapets on the top of the city wall.
