I used to believe TV commercials featuring celebrities and although I didn't always buy their merchandise, I did usually form a good impression of the companies after seeing them on TV.

But when former CCTV host Zhao Zhongxiang apologized for appearing in a fake medicine advertisement last week, I realized I had been wrong. There is no doubt that some celebrities have immorally lifted the quality of the products. They praise the effects of products with beautiful words and encourage consumers to buy. The truth is, though, they often haven't ever used them.

It is now easy to understand why so many people single out celebrities and lash out at them. But I would like to add that TV stations should also be held responsible for their promotions.
