Why are flights from Harbin to Changsha cancelled frequently?

The frequent cancellation of flights from Harbin to Changsha is due to the epidemic situation. Recently, a large number of airport flights have been cancelled in many places in China, mainly due to the outbreak of the COVID-19 epidemic. Due to the impact of the epidemic, in order to avoid the spread of the epidemic becoming more serious, in view of the serious situation of the epidemic, the flight of the plane was temporarily suspended. At the same time, after the outbreak, many people reduced their travel, resulting in a small number of passengers, which eventually led to a targeted reduction in the number of flights at various airports. Therefore, the frequent cancellation of flights from Harbin to Changsha was due to the epidemic.
