On Valentine's Day, campaigners took to the streets in Beijing's historic Qianmen district, just south of Tiananmen Square to call for the legalization of same sex marriage and a greater acceptance of homosexuality. Male and female couples, dressed in their wedding best, staged mock photo shoots drawing gasps, smiles and the odd scowl for passersby.
