The application operator should also conduct a survey and control the hotels that are promoted and sold through the application. For example, this hotel is very, very inconsistent with the photos shown (dirty and the facilities are far from feasible), not to mention there is an additional room price from the price that has been paid by consumers. The question is, is it not a lie in the price of the application, because at check-in there is an additional price (I ordered 2 rooms for an additional 300,000). .
