"I'm from Guangdong. I'm one of the online construction supervisors," wrote one netizen in a comment below the livestream. Another wrote,"Best wishes to the people of Wuhan, and good luck to all of us."

Peng, the wastewater disposal expert, was born and raised in Wuhan. He lives in the downtown with his parents, wife, 10-year-old son and 3-year-old daughter.

He has instructed his family not to leave the house, but he has been working at the construction site at least 12 hours a day for the past nine days.

He said he likes the names of the Huoshenshan and Leishenshan－"Fire God Mountain" and "Thunder God Mountain"－hospitals. In traditional Chinese culture, the fire god drives away plague, while the thunder god punishes demons.

"They are very appropriate names. They represent our virus-fighting spirit," he said. "Wuhan will definitely recover."
