Xiaofei, a fourth-year female student at a university in Changchun, gave up continuing to prepare for the postgraduate entrance examination and chose to open a sex products shop instead. With the help of her parents, she invested 140,000 yuan in February this year and started a sex products store in a bustling area of Changchun. The products include SM tools, sex toys and lingerie. Since its opening, the small store has been doing pretty well. The customers include white collars, middle-aged couples and elderly people.
