Courtyard by Marriott Nanchang has more invoices.

Sorry, I don't know how much Nanchang Marriott Hotel overcharged. However, according to the general tax regulations, false invoicing is an act of false invoicing, which violates the provisions of the tax law. If you are asked to invoice more when staying at Courtyard by Marriott Nanchang, I suggest you communicate with the hotel. If you can't get a reasonable explanation, you can complain to the tax authorities.
