Hehehehehe, it must be invoiced. This is stipulated by the state, and the act of not issuing invoices is tax evasion. The invoice issued by the hotel reflects two taxes: 1, business tax (or value-added tax), and the tax rate is 5.5(3.0, 5.0); Additional tax, the tax rate is 5% ~ 7% of the business tax; 2. Income tax and tax rate vary with the amount, and are generally determined by multiplying the amount on the invoice by 25%. (If it is VAT, it should be: the amount on the invoice minus VAT times 25%)

Hehehehehe, I hope I can help you.
