The court in Aba prefecture, a remote rural area in the south-west of Sichuan province where a large number of ethnic Tibetans live, said Tang deserved “severe punishment” in accordance with the law.
After her death tens of thousands of her followers left messages on her Douyin page, while millions of users of the microblogging platform Weibo called for justice using hashtags that were later censored.
China criminalised domestic violence in 2016 but it remains widespread, particularly in rural areas.
Lamu is reported to have approached police repeatedly about Tang’s violence towards her, but officers rebuffed her saying the violence was a “family matter”.
She then divorced Tang but returned to him after he threatened to kill one of their children. After the beatings continued she divorced him for a second time and gained custody of both children.
About a quarter of married women in China have experienced domestic abuse, according to a 2013 study by the All-China Women’s Federation.
Some activists fear that a recently introduced mandatory 30-day “cooling off” period for couples who wish to divorce may make it harder for women to leave abusive relationships.
