Book a hotel online, issue an invoice on the same day, and leave the hotel the next day to open another ticket to check out.

Of course. You can ask the hotel to open another one. If it doesn't work, it will be more troublesome to reopen the hotel. The invoice reimbursement period is half a year, and the invoice reimbursement should be in the month when the invoice is issued or as soon as possible. But not in the new year. Tax adjustment is needed for Chinese New Year reimbursement. Theoretically, all invoices of that year can be reimbursed.
