First of all, Ctrip should have a platform for these hotels and hotel merchants to upload information independently and then manage it in a unified way. In fact, it means something like a supermarket. When you put all your products, that is, accommodation and catering services, to me, I will provide you with a high prestige and high participation platform to help you promote them. I guess these hotels should pay for Ctrip, which actually means the same as spending money on advertising.
Then there are some big popular hotels. For example, the seven-day Hanting Hotel, such as Home Inn, or those big 4-star hotels, I think it is likely to be a cooperative relationship with Ctrip. I always think that Ctrip's scoring system can do a lot of articles. After all, there is no open and transparent publicity on how to evaluate the scores. So similar to a search engine, I will give you priority display if you pay. Ctrip itself needs these famous hotels to help win customers.
The above is my own opinion, which may not be accurate. I hope I can get your adoption! ~ thank you! ~~
