Several Chinese feminist channels on Douban, a popular social networking forum in China, were abruptly shut this week, triggering online anger and prompting calls for women to "stick together."

Douban has closed at least eight feminist channels, citing extremism, radical political views and ideological content, women's rights supporter Zhou Xiaoxuan wrote on social media.

"I firmly support my sisters on Douban, and oppose Douban's cancellation of feminist channels," said Zhou, who in 2018 filed a sexual assault suit against a national TV anchor, fueling China's #MeToo movement.
