Some hair salons have opened their doors in Changsha amid the novel coronavirus epidemic cautiously as Monday marks Longtaitou Day. The day of Longtaitou, which literally means "dragon raises head", falls on the second day of the second lunar month. Traditionally, it is a busy day for hair salons as many Chinese believe that a new hairdo on that day will bring good luck. (Xinhua/Xue Yuge)
