There is no problem with the household registration book, but there is no household registration book, which needs to be copied and sent to me. The pages of the household registration book and the pages of passengers can be used as temporary boarding passes at the airport. Every airport plane has a temporary boarding pass. If you don't line up, it will take a few minutes. Note (the account book or a copy of the account book should be used as a temporary boarding pass) before you can change your boarding pass. (if it is a copy of the household registration book, it is mainly to copy the page of the household registration book. I hope I can help you.
