Women, wearing nylon masks, rest on the shore as youths walk past them during their 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.
