Chinese are becoming less likely to view sex as a taboo subject thanks to social and economic development.
That tendency was evident at a sex cultural fair being held June 6-10 in Xi'an, capital of northwest China's Shaanxi province.
Deng Jianfeng, project manager of the event, said the fair attracted more than 20,000 visitors on each of the first three days. About 70 percent were middle-aged and elderly people.
About 30 people lined up in the hot sunshine in front of the fair's ticket office to buy admission to the event and obtain a free booklet titled "Knowledge About Sex".
The fair presented an exhibition of ancient sexual artifacts, an exhibition of sexual arts and painting, a sexy lingerie show, an exhibition of ancient Chinese erotic pictures, seminars on sexual knowledge and an exhibition of nude photography, the daily said.
