What is the inter-provincial travel fuse mechanism?

the "fuse mechanism" of inter-provincial tourism refers to the immediate suspension of travel agencies and online travel enterprises from operating inter-provincial group tours and air tickets plus hotels in provinces with medium and high-risk areas. The purpose of this is very clear, that is, to stop the further spread and spread of the epidemic and prevent the epidemic from leaking out.
