沙海: 沙蟒蛇巢

In a winter of 1980s, many Red Flag cars turned up in Beijing and brought some children with outstanding talent in architecture into Badain Jaran Desert, and the children never showed up in the following 30 years. An ancient architectural design drawing of 1900 years old is exactly similar to an industrial ruin in Badain Jaran Desert, and in the process of investigating the ruin, some people found the missing childrens names.
