When Xu He watched the video of his four-year-old son speaking these words, he could only wipe tears from his eyes.

Xu, 33, a civil servant in Diaobingshan, Northeast China's Liaoning province, has worked for more than two weeks helping fight the novel coronavirus outbreak.

During work in a community, he visited hundreds of families to investigate visitors from other cities.

"I had been a policeman before, so I believe I can fulfill the task well," he said.
