Sun Dongfang is a policeman in Zhengzhou City, central China's Henan Province. He has been working on the frontline in the fight against the ongoing coronavirus outbreak and hasn't been home in over ten days. Recently, he missed lunchtime at work so he asked his wife to drop a bento box down on a rope instead of going home. As a special way of saying "goodbye," Sun and his son saluted each other in the end.
