Can I cancel the bad reviews given by guests on Ctrip?

Hello, after giving a bad review to the hotel, guests can't cancel or modify the rating on the website by themselves, but they can add comments within 30 days. Subsequent comments can only add comments, but they can't modify the rating. Guests can only contact Ctrip customer service, call Ctrip customer service hotline 10 106666, switch to 1 and enter the hotel channel, explaining to customer service to delete the bad reviews. Ctrip will hide the bad review display of the external network, and the processing time is within 1 day. Learn more about OTA operation knowledge and pay attention to Fire B&B.
