He is a "doctor", specializing in the strange and difficult cases of the architectural world. He dares to move skyscrapers weighing thousands of tons by dozens of meters, and even make them turn around; In order to allow the subway to pass smoothly through the downtown area, he dares to neatly cut off the foundation of the buildings on the ground, and then install a new "throne"; He is more like a doctor who brings countless buildings suffering from "cracks, leaks, sinking, and tilting" back to life... He is Li Guoxiong, known as Guangzhou's "Modern Lu Ban".
