昆明湖
The Long Corridor leads from the "Gate for Greeting the Moon" (Yao Yue Men) in the east westwards along the northern shore of Kunming Lake. Along its entire length, it keeps to the transitional zone between the lake shore and the foot of the Longevity Hill, which is on the opposite side of the corridor. The Marble Boat, a landmark lakeside pavilion, is located near the western end of the corridor. The middle section of the Long Corridor passes in a southward bend around the central building complex on the lake side of Longevity Hill, The main hall in this complex is the "Cloud-Dispelling Hall" (Pai Yun Dian), where the Empress Dowager Cixi used to celebrate her birthday. The Long Corridor runs through the "Cloud-Dispelling Gate" (Pai Yun Men) that marks the center of the corridor. The Gate is a landmark in its own right and covered in paintings.
