Below is a passage adapted from the network edition of China Daily.

                                                                       Event

     Li Yang, one of China's most famous English teachers, apologized for beating his American wife more

than a week after she posted photos of her injuries on the web and set off a bomb of criticism.  "I

wholeheartedly apologize to my wife Kim and my girls for committing domestic violence. This has caused

them serious physical and mental damage," Li said on his mieroblog at Weibo.com, the country's most

popular social media site, on Saturday. Li, 42, is a mechanics major but is best known for his "Crazy

English," a popular method of language learning that involves yelling at the top of one's lungs.  He was at

the center of public criticism after his wife Kim Lee put up posts on the web accusing him of abuse,

showing her swollen forehead and knees.

                                                                    Voices

     @Xuemanzi, angel investor  Anti-domestic violence laws should be made as soon as possible, giving

protection to the rights of women and children lawfully. Police should not stand back from domestic

violence any longer, even if no one reports them. Society, as a whole, should attach greater importance to

the crime.  @Zhangxiaomei  Chinese are never taught about marital(婚姻的) relations, which mean not

merely living together. A good marriage needs to overcome three differences: family background, gender

and personalities. In addition to these, there is cultural gap in Li Yang's case. If the effects of these

differences are not well understood, after the honeymoon period, they will turn into conflicts and endanger

the marriage. Li's domestic violence is a reminder that China needs such education.  @Wuxiaolong,

Sina Weibo user  Li Yang's choice to resort to domestic violence really reflects his character. Students

who have attended his Crazy English Camp may know what I mean: Li wants his students to worship him

as an idol. I still remember he once had his students kowtow to him. He always teaches English by

imposition(权威强制), which directly reflects his desire for power.  @Sikaozhe, Sina Weibo user  In the US, the punishments for domestic violence are even more severe than strealing. If the police arrive at the

wife's call during a fighting between a couple nd find injuries on her, they will immediately arrest the

husband. Even if the wife doesn't call the police, they may also show up as neighbors could well do their

part.  @ykxin Sina Weibo User  Don't blindly worship anyone, because in every closet there may hide

a skeleton. As a famous Chinese saying goes, "Only they who do well in their daily routine tasks can

fulfills their dreams on great occasions". Not surprisingly, one who focuses too much on his career and

ignores his family, like Li Yang, will fail in both. Don't judge a person by his career success, wealth, or

any other material aspect, because what finally decides a person is his character.

                                                             Aftermath(余波)

     Although Li Yang publicly apologized to his wife, promising to love his daughters even if he and Lee

divorce, the damage, perhaps permanently, has been done to his wife, his three daughters and the whole

family.  Wang Xingjuan, founder of the Maple Women's Psychological Consulting Center, a non-profit

organization, said nearly half of domestic violence abusers are people who have higher education, senior

jobs and social status. She said this was probably because such people were usually under more mental

stress.
