There are two sections of the Great Wall in the Suizhong county. One lies at the southwest boundary of Lijia, Yong’an and Jiabeiyan town, with the total length of 31 kilometers. It was built on the fourteenth year of Hongwu’s reign in the Ming Dynasty, which belongs to the Jiliao Great Wall, the main trunk of the Ming Great Wall. Another one belongs to the Liaodong Great Wall, the branch of the Ming Great Wall. This section of the Great Wall was built on the fifth year of Wanli’s reign in the Ming Dynasty. 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. There is a rampart every 250 meters to 500 meters apart, and a sentry building every 500 meters to 1000 meters. Passes were also built at the entrances and valleys.
