In China visitors can get a pre-paid postcard as the ticket in most of scenic areas. My friend Liu Zheng sent this ticket when he was by the Simatai Great Wall. On the view side you may find the World Heritage log and on the back you may also see the simplified map.
Simatai is a section of the Great Wall of China located in the north of Miyun County, 120 km northeast of Beijing, holds the access to Gubeikou, a strategic pass in the eastern part of the Great Wall. Originally built during the Northern Qi danysty (550-577) and rebuilt in the Hongwu years of the Ming danysty by Qi Jiguang, this section of Great Wall is one of the few to retain the original features of the Ming dynasty Great Wall.
Simatai Great Wall is 5.4 km long with 35 beacon towers. This section of the Great Wall incorporated the different characteristics of each section of the Great Wall. A specialist on the Great Wall, Professor Luo Zhewen, has said "The Great Wall is the best of the Chinese buildings, and Simatai is the best of the Great Wall." UNESCO has designated Simatai Great Wall as one of the World Cultural Heritage sites.
