My friend asked me to book a hotel in Shanghai, and my colleague recommended the same journey. Said you could use cash coupons. Is it cheap directly? Seeking the truth

A cash coupon is a product with the word "return" that you ordered online. The system will automatically help you use the same amount of cash coupons to "return". After you check in, the system will "return" the previously used cash 30 to your Tongcheng account as a reward in the form of review bonus. When the bonus reaches 200 pounds, you can apply to withdraw the bonus. Because the cash coupon is a discount for you on the same trip. Com, has nothing to do with the hotel, so you can't directly deduct the room rate at the hotel, nor can you refund it.

Thank you for your support of Tongcheng.
