The Long Corridor (Changlang), 728 meters (796 yards) in length, is the longest of its kind not only in China but also in the world. In 1992, it was put into the Guinness World Record as the longest corridor of the world. Running from the Yaoyuemen (Gate of Inviting the Moon) in the east to the Shizhang Pavilion in the west, the corridor includes 273 sections, all decorated with paintings. Along the corridor, four elegant octagonal pavilions are interspersed in order, each of which symbolizes one season of a year.

The corridor is also an exceptional art gallery, featuring more than 14,000 pictures of landscapes, flowers, birds, human figures and stories on its beams and ceilings. It is an excellent carrier of the Chinese culture, including traditional art, history and literature. Of special note are the pictures of human figures depicting stories that give a lively account of long history of China. As there isn't additional explanation in the pictures, visitors have to imagine what the picture is about from people's expression, costumes, acts and the narrative scenes.

The corridor wanders westward from the Court Area, along the north bank of the Kunming Lake, at the foot of the Longevity Hill. It is virtually a smart connecter of the three scenic areas in the Summer Palace, which make it a primary route for visiting the whole garden, rain or shine.
