Certain bus services in downtown Kunming were resumed on February 22, following a notice issued by local authorities. 

Given the ongoing COVID-19 epidemic, stringent measures are still in force: All passengers shall wear masks and scan a QR code to have their rides recorded. 

For the seniors who do not use a smart phone to scan the code, the conductor has to write down their name, ID and phone numbers.

Also, only a limited number of buses run on major lines and they stop at chosen stations.
