The letter also called for the NPC Standing Committee to make public what work has been done so far, and proposed giving more resources to grassroots organizations to participate in the fight against domestic violence.
Li Yueyang, director of the legal department at the All China Women's Federation, said a poll of more than 1,000 people in 20 provinces last year found 93.5 percent support the introduction of a domestic violence law.
The standing committee has included making a dedicated law in its legislative agenda this year, she said at a symposium in Shenzhen, Guangdong province, on Saturday.
At the forum, experts, officials and social workers from the Chinese mainland, Taiwan, Hong Kong and Macao shared their research and experiences in the field.
