File photo taken on June 10, 2016 shows the renovated Qilou ancient street 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/Yang Guanyu)
