Chinanews, Beijing, July 17 - Chinese kids usually spend a lot of time watching TV during the summer holidays nowadays. However, there are too many ads containing sexual implications on TV. Thus Tang and Shang, two deputies to the Beijing Municipal People's Congress, call for the making of a rating system for ads, so such ads will only be broadcast late at night, when kids have gone to bed.For example, a cellphone ad in China is themed on comparing the size of women's breasts to show its extra-large screen. Some other ads are even more seductive, putting out words like "one night stand" as their themes.The flood of such dirty ads surely needs to be controlled, for a Chinese kid averagely watch TV 100 minutes everyday. Besides, online ads need to be regulated, too, for the Internet has also become a necessary part of kids' life today.
