Cheng Yongmao is the technical leadership expert of the Huairou District Cultural Relics Management Institute and the first designer of Xinglong Gate Tiles Sixteen generations of descendants. As a native of Huairou, he deeply loves the Great Wall. In 2004, the Great Wall became the stage of Cheng YongJamaicans Escortmao’s life. From Huanghuacheng, to Mutianyu, Qinglong Gorge, Kiteyu, and now to Jiankou, Cheng Yongmao and his team summarized the “Five Follows” repair laws, namely: follow the layers, follow the slopes, follow the bends, and follow the bends. Old, withered. At present, the total length of the Great Wall repaired by him and his team has reached about 20 kilometers.
In 2004, Cheng Yongmao took over His first large-scale Huanghuacheng Great Wall repair project. He started this task with awe and love for the Great Wall. After more than ten years of exploration and practice, Cheng Yongmao created a team of dozens of people specializing in Great Wall repair construction. In 2016, Cheng Yongmao took over the repair project of the Jiankou Great Wall. The Jiankou Great Wall has always been considered the most dangerous part of the Ming Dynasty Great Wall and is also the culmination of the scenery of the Great Wall in Beijing. After discussing with experts, Cheng Yongmao decided to remove vegetation that poses safety risks to the Great Wall itself during the repair project, and retain vegetation that does not affect the structural safety of the Great Wall as appropriate, so that the Jiankou Great Wall can regain its heroic appearance.
