Do I need a travel code to stay in a hotel now?

In the dangerous period when the epidemic still exists, all public places must register all personnel in detail according to the requirements of the national epidemic prevention department. Regular hotels will basically show your travel itinerary code when you check in. In order to know whether you have passed through or stayed in an epidemic-prone area, so as to make corresponding treatment. And some remote hotels that basically don't check may have some negligence in this respect and won't check your itinerary code.
