Population mobility to other cities from Wuhan was restricted on January 23, 2020, and all the inhabitants have been affected to either go out or come back to the city ever since. Vehicle transportations in Wuhan such as city buses and subways were banned and outbound transportations have been canceled (airlines, trains, and long-distance buses). In many places, the Chinese Lunar New Year Festival celebration and other gatherings were cancelled to reduce population concentration. Besides, Wuhan not only imposed a ban on overseas travels for tour purposes, but also suspended selling flight tickets and hotel-booking.
