A tourist takes pictures of herself with a house made from oyster shells in Quanzhou, Fujian province. In the region, oyster shells are often used by locals as a building material. The resultant waterproof and moth-proof homes are a unique local feature, attracting visitors to enjoy their special beauty. Currently, there are around 100 "oyster houses" left in Quanzhou, recognized as cultural relic protection sites. (Xinhua)
