The education bureau of Xinzheng, Henan province, confirmed on Wednesday that a local teacher had died after teaching a class online.
The death of Liu Hanbo, a history teacher at Xinzheng No 3 High School, happened after she finished an online course at home on Friday, and local police have confirmed it was not a criminal case, according to a statement posted by the city's publicity department on microblogging platform Sina Weibo.
The case aroused widespread public attention after Liu's daughter claimed that her mother died alone at home on Friday. She said her mother had suffered from online bullying after high schools citywide were required to teach classes online in the middle of last month.
It is not suggested that online bullying was a contributing factor in the death.
"I was told my mom's news two days after her death, because my dad, younger sister and I were all busy with study and work outside of the city," Liu's daughter said in her post on Sina Weibo.
She provided a video clip and said that a few internet users entered the online room and disturbed the order of the class by various means, such as by playing noisy music and being rude, while her mother livestreamed her class on Friday evening.
