A woman, wearing a nylon mask, creates a circle in the sand as she lies down during her visit to a beach in Qingdao, Shandong province July 6, 2012. The mask, which was invented by a woman about seven years ago, is used to block the sun's rays. The mask is under mass production and is on sale at local swimwear stores.
