Residents of the northeastern Chinese city of Harbin who volunteer to take a Covid-19 test and get a positive result will receive a reward of 10,000 yuan ($1,570), local authorities announced Thursday on the messaging and social network app WeChat.

According to data from the government of Harbin, three cases of Covid-19 were detected Thursday that would be related to the case rebound in the city of Manzhouli, Inner Mongolia, where there are 185 active infections.

The decision of the authorities, which aim to block the "transmission channels" of the virus, has attracted the attention of Chinese netizens and a hashtag, which translates to "Harbin will reward 10,000 yuan to people who undergo a test and give positive result," has accumulated more than 100 million views on the Weibo social network, similar to Twitter.
