"Doujin", the Chinese version of "Tik-Tok", will limit the time of use of its platform for children to 40 minutes a day.
The new rule applies to users under the age of 14, who are authenticated by their personal names, and they will be able to spend 40 minutes from 6 a.m. to 22 p.m.
The company Bytedance, which owns Doujin, announced the new rule in a blog, noting that it is the first application of its kind to introduce such a restriction.
The move comes as China works hard to limit teenagers' time on video games and social media.
