A local court in Central China's Henan Province has accepted the lawsuit filed by him against the Second People's Hospital of Zhumadian where he was hospitalised for 19 days by his family members on October 8 after he filed for divorce from his wife.
During his time at the hospital he was made to receive injections and take medicines such as antidepressants.
"They did it simply because I am gay," the man was quoted as saying by state-run Global Times.
He was rescued from the hospital on October 26 by local police, who had been alerted to his plight by a gay rights activist.
