A man holds up a sign displaying his unmarried son's information at a matchmaking fair held by the local Women's Federation in Harbin, capital of Northeast China's Heilongjiang province, Aug 6, 2011. The day marks Qixi, the Chinese Lovers Day, which in the Chinese lunar calendar falls on July 7. Such matchmaking fairs attract not only single men and women who hope to find their other halves, but also parents who put up advertisements for their unmarried adult children, hoping to find a son or daughter-in-law soon.
