Tampons first went on sale in China in 1985. But many Chinese women, especially in rural areas still didn't have access to basic sanitary products.

Yashan Zhao has been talking to the man behind the first advertising campaign for tampons in China, and to a woman from the countryside where sanitary products were not widely available until the late 1980s.
