When Xia Min started drinking alcohol with her classmates at a friend’s birthday, she didn’t realize what would happen to her. She drank a lot and fell into a coma (昏迷). The 15year-old girl from Chongqing never recovered.

Xia’s death is warning to other students. A new rule went into effect on January 1, 2006. Teens are not allowed to buy or drink alcohol. Shops are not allowed to sell it to them.

A 1999 Chinese law forbade (禁止) shops to sell alcohol to youths under 18. But it is not taken seriously by shopkeepers because it doesn’t have specific rules. People hope the new rule will work.

“I tasted alcohol when having the dinner of the last New Year’s Eve,” said Lian Yuqi, a 16-year-old girl in Xiamen. She believes that the new rule will stop teens from drinking and help them grow in a healthy way.

“Although it may be a little disappointing not to have beer at parties, I think we can have soft drinks instead,” she said.
