So Vivian Hsu is doing promotion for the 2010 movie "Hot Summer Days" (全城熱戀).
I'll translate the relevant section from this Sina article.
Wearing a sexy black form-fitting outfit, Vivian Hsu plays a character named "Wasabi", a passionate rich woman. Her love interest "Soy Sauce" is played by Daniel Wu.
Regarding the experience of playing a rich woman, Vivian laughed and said she had never had such good treatment. "The sushi store in the film is one opened by the director and Daniel Wu. The sushi there is delicious. Since I"m playing a rich woman, every day I get to wear beautiful clothes and go eat delicious sushi, and then afterwards I get to live in a 5-star hotel. But because I'm afraid of getting fat, the second the director yells cut, I go throw up the sushi. I truly eat too much.
At this, the investment boss Mr. Fang sitting nearby suddenly saw the light and said, "No wonder the expenses have been so high!"
Emphasis mine. The article goes sailing right by this and starts to natter on about Daniel and Vivian's kissing scenes and I'm going "Back the HELL up now, this is a major star, someone a lot of girls look up to, she treats bulimia like a good weight loss strategy, and NOBODY CARES???"
I don't understand Chinese media at all.
A blurry photograph of a star having some kind of consensual romantic relationship with another adult: OMG SCANDAL MAYHEM THINK OF THE CHILDREN YOU SLUT
A star blithely says she throws up to stay thin: *crickets*
