You can't buy it until you register. The payment methods include Alipay, Tenpay and online banking of all banks. After the purchase is successful, you will receive a short message voucher (you can also print the consumption voucher online), and then take the short message to the merchant (the hotel you bought) to spend. As for the hotel, don't worry about it. They have already communicated. I often organize things on Handan. I hope I can help you.
