Is it necessary to say the tax-included price in advance for the hotel price?

The price of staying in a hotel needs to include tax in advance.

You can't hide customers, it's illegal.

The prices we usually live in are tax-inclusive, including business tax. In fact, it is illegal for them to distinguish business tax in this way.

The tax law stipulates that the business tax shall be borne by the hotel, but now the hotel collects business tax under other flags. They are just careless and let everyone think it is value-added tax. Value-added tax is a tax directly passed on to consumers.
