Is the 3 days in the tourist hotel on Douyin real?

Fake, the 3-day tourist hotel on Douyin is fake. After checking the Black Cat Complaint Platform, it was found that on August 10, 2022, someone purchased a group purchase of the Crowne Plaza Qiandao Lake Hotel on Douyin for 3 days and two nights with a flash sale of 100. After contacting the front desk online to make a reservation, the reservation department informed that they needed to know the coupon code before they could make the reservation. After I informed them of the coupon code, the hotel told me that I did not have such a write-off order and could not make the reservation. They told me that it was a problem with Douyin's backend write-off system. Later, I contacted Douyin customer service and informed Douyin customer service of the coupon code and asked the customer service to help me contact the merchant. The order was confirmed, but the merchant did not recognize the verification code and insisted that the backend system could not recognize the coupon code and could not cancel it.
