Is there really a discount for saving money by using koi fish to get stuck in a hotel?

There is a real discount. There are many hotels to choose from on koi fish Card app, such as Jinjiang Hotel, Meituan Hotel, Yatuo Hotel and so on. Take Meituan Hotel as an example. You can get a red envelope when you place an order in 25 yuan, which does not conflict with the hotel's own discount. In addition, you can get a maximum cash back of 4% after placing an order, so you can save a bag of money and use it conveniently if you book it at Meituan Hotel ~
