With 34.7 percent of Chinese families reporting incidents of domestic abuse, Chinese marriage law experts on Thursday called for legislation on domestic violence.

Xia Hongyu, a resident of Lichuan in Hubei province, relates how her ex-husband gouged out one of her eyeballs in December 2004.

"National legislation to combat domestic violence is badly in need, because existing articles of law do not provide a sufficient legal basis for timely and effective judicial intervention," Li Mingshun, deputy head of the marriage and family board of the China Law Society, said at a conference in Beijing marking International Day for the Elimination of Violence Against Women, which fell on Thursday.

The conference was jointly hosted by the All-China Women's Federation (ACWF) and the United Nations in China.

"We have been receiving more and more complaints about domestic violence in recent years, despite 27 provincial-level governments having made considerable effort to enact local regulations against this problem," said Meng Xiaosi, vice-president of the ACWF.

The ACWF has annually received 40,000 to 50,000 complaints about domestic violence since 2004. According to research by the China Law Society, 85.4 percent of these cases involve husbands acting violently toward their wives.

These women suffer physical, psychological and sexual abuse an average of 7.4 times a year, according to data from women's organization in Henan, Beijing, Jiangsu, Shandong, Hubei, Liaoning and Hebei. The reasons for the abuse range from infertility, giving birth to a daughter and husbands engaging in excessive drinking.

"The main difficulty in suing a family member for abuse is producing the evidence," said Jiang Yue, a professor of marriage and family law at Xiamen University.

To obtain a divorce for domestic violence in China, civil law requires a wife to be able to prove in court that her husband beat her, though any injuries that she may have sustained have usually healed by the time the hearing is held, Jiang pointed out.
