You can't buy until you register. Payment methods include Alipay, Tenpay and online banking of all banks. After the purchase is successful, you will receive the SMS voucher (you can also print the consumption voucher online), and then take the SMS to the merchant (the hotel you purchased) for consumption. As for the hotel, you don't have to worry. They have already communicated. I often arrange things in Handan. I hope I can help you.
