Spas, cinemas and mahjong salons in the Chinese city of Harbin were ordered to close to prevent Covid-19 spreading in poorly ventilated spaces, state television reported.
The temporary shutdowns were part of a range of restrictions imposed on the northeastern city after one case of community transmission, the report said, citing the Harbin government.
Religious activities were also suspended, tourist attractions were ordered to operate at half capacity, and visits were banned at retirement homes.
The restrictions come as China celebrates the mid-moon festival and ahead of the National Day golden week holiday starting on 1 October, a time of increased travel and social interaction.
