In June 2012, a post titled "Shanghai Rich Girl Yang Liling Goes to Japan to Experience Being an Actress" went viral on the Internet, claiming that Shanghai rich girl Yang Liling went to Japan to shoot AV, and a Japanese version of the video was leaked. Yang Liling is called "the first Shanghai woman to shoot Japanese AV" by netizens.
However, some netizens judged based on Yang Liling's Japanese and Chinese pronunciation in the film that Yang Liling should be Japanese, and the so-called "Shanghai rich girl" status is just an excuse for the Japanese film studio to create hype.
