"Mom, I'm here to take you home." At about 12:00 at noon on August 13, as the bus carrying medical staff slowly drove into the building of the Zhongshan Health Bureau, Guo Bin, an ER physician of Dachong Hospital, who had been waiting for a long time, trotted forward with his two sons. The children hugged their mother Zhang Songling tightly.

In June this year, 60 medical staff were selected to support sampling at Guangzhou Baiyun International Airport. They worked diligently day and night for 66 consecutive days, and sampling nearly 30,000 passengers.

The 60 anti-epidemic heroes did excellent jobs and returned to Zhongshan on August 13. Some of the medical staff said that they would return to their hospital posts to continue their jobs in epidemic prevention and control, and safeguard the people's health.
