Why can't Tongcheng? Com merchants modify the price to delete the room type?

Hello, I seem to have encountered your problem before. The following are my original solutions and methods. I hope I can help you. Please forgive me if there is any mistake! The price is different because the hotel and Tongcheng do different activities. In order to promote the sales of the same room type, he may have online price, group purchase price, half price and surrounding price. You can choose the lowest price to stay! Thank you very much for your patience. Please adopt it if it helps. Wish you a happy life! thank you
