Self-protection period of Simatai Great Wall

At the beginning of 1985, Yu Yingshi and Li Geng in charge of planning Beijing tourism believed that the inclination to destroy the historic relics is wrong in protecting the Great Wall and developing tourist spot, because they thought the development should not always try to please all visitors by allowing service facilities in the main part of the relics. They proposed to combine the protection with prospective design and establish a zone for comprehensive protection of the Ming Great Wall.
After a year of feasibility study, they concluded that the Simatai Great Wall has unique features and breathtaking landscape and, more importantly, the original Ming style. They considered the Simatai Great Wall qualified for realizing the designers' ideas.
In February 1986, the state council approved the plan to protect the Ming Dynasty Simatai Great Wall, and the task was assigned to Beijing municipal government. This marked the Simatai Great Wall first part of Ming Great Wall under protection in China. The state council also decided to spare special funds for repairing the roads of the area and asked the State Administration of Cultural Heritage and Beijing municipal government to draft a specific plan for development and construction.
Later, experts, central and local government and research institutes conducted thorough discussion to come up with better themes and technological solutions. Luo Zhewen, a famous Great Wall expert, believed that the original design is well-grounded according to field research and offered important suggestions to the plan.
From 21st March to 5th April 1988, UNESCO and ICCROM sent a six-people reviewing team to consider the listing of World Heritage in China. On 24th February, the team visited the Simatai Great Wall recommended by the State Administration of Cultural Heritage.
They pointed out that the reconstruction was satisfying and complied with relative international principles. Their praise was the only positive one after they visited three cultural sites in Beijing area listed on The World Heritage List.
