Yan Libin, who had been working as a medical volunteer in Wuhan for 43 days, now volunteers to work at Suifenhe makeshift hospital in Northeast China's Heilongjiang province.

"I've gained some experiences in Wuhan. I hope that I can do more for the fight against COVID-19," said Yan, 21, as she stepped onto the train headed to Heilongjiang on April 22 from her hometown Dalian, in Northeast China's Liaoning province.

"Last time, when I left home for Wuhan, I knew nothing, even about how to protect myself. This time, I think I can help local medical workers take care of patients immediately," she said.

Yan applied to be a volunteer on Feb 13 and went to Wuhan three days later. She first worked at a quarantine hotel, taking care of the daily needs of people under medical observation. Later, she was designated to work at Wuhan Leishenshan Hospital, where medical workers from her hometown, Dalian, were.

Yan said when she was in Wuhan, she worked more than 15 hours each day. On March 30, she returned to Dalian with the city's 529 medical workers supporting Wuhan.

"Protect yourself. We're proud that you're helping others," her parents said before she left home again.

"I hope we win the fight against the epidemic as soon as possible and look forward to seeing people take off facial masks and laugh happily," Yan said.
