The coronavirus lockdown may be over in Wuhan, but in another part of China, it appears to be just getting started.

Suifenhe, a city along China’s northern border with Russia, is now ordering residents to stay inside and only go outside for necessities once every three days, Reuters reports, citing state media.

The restrictive measures were issued after provincial health officials reported 25 new coronavirus cases there Tuesday, spurred by people entering China through a border checkpoint.
