A 1,000-square-meter COVID-19 mass testing site was constructed within 6 hours on Monday, in Guangzhou, capital of South China's Guangdong Province.

The Chinese mainland on Tuesday reported 10 new locally transmitted COVID-19 cases in Guangdong Province, the National Health Commission said in its daily report on Wednesday.

Guangzhou is carrying out mass COVID-19 nucleic acid tests for citizens in order to contain the resurgence of the virus.

Starting from Sunday, mass testing in Guangzhou will expand from Liwan District to Yuexiu District and Haizhu District, as well as key areas in the districts of Tianhe, Baiyun and Panyu.
