A look at Qilou ancient street in China's Hainan

File photo taken on Aug. 14, 2012 shows the Qilou buildings in Haikou, capital of south China's Hainan Province. Nanyang-style Qilou buildings are balcony-type tenant buildings for both residential and commercial use. The first floor of a Qilou house is used as a shop, and part of the second floor hangs over the first floor and is supported by columns, forming a shelter in front of the shop. People live on the upper floors. Qilou houses line up to form a shopping street, leaving overhangs on both sides of the street to shelter pedestrians. (Xinhua/Guo Cheng)
