Interesting !
Tell us how the process goes

I used Google translate to get around the site, it runs quite well! Confirming your registration on their Website is done by SMS (there is an option for email registration but it didn't work for me...)
You can only pay by Credit Card. There is an Option for "Paypal" but that's Google translate mixing up the Chinese equivalent of PayPal, Alipay with the western used PayPal! After that it will automatically register you to Alipay, where, when you are prompted on your profile page, will need to confirm the payment. After that you just have to wait the 3 weeks (depends !).
