Can I use koi fish to jam the hotel? Save money?

If available, take Meituan Hotel as an example. You can get the hotel general red envelope on koi fish Card app in 25 yuan, and you can enjoy up to 4% cashback after placing an order. In addition, there is no conflict between red envelopes and concessions, that is, red envelopes can be used on the basis of concessions, which is very grounded and is what everyone wants to see most. The more you save, the better!
