Introduction to Chairman Mao Zedong’s landline: Today, the cabin has been restored to the original state when Chairman Mao was riding on it. The color photo of "Mao Zedong at Work in the Aircraft" hanging on the bulkhead is particularly eye-catching. It was the autumn of 1957. Mao Zedong took this plane to inspect Shandong and then continued southward. During the voyage, he was wearing a gray coat and leaning on a small square table. He held a cigarette in his left hand, which was lingering and burning, and he held a pen in his right hand, holding it in the air, and he was concentrating on correcting a piece of material. Hou Bo, Mao Zedong's full-time photojournalist, captured and captured this precious shot in time, vividly reproducing the image of Mao Zedong as a great man who took care of everything for the people.
