A major restoration project to protect the walls of the Palace Museum in Beijing, also known as the Forbidden City, begins on November 26, 2016, which aims to fix the diseases of "old age" that threaten the 600-year-old imperial structure. It is the biggest restoration project at the museum since 1949. The first phase has already begun on a 233-meter section of the wall at the western end of the complex named Xihuamen, which is the part most affected. (Photo/CFP)
