Banana Project has assigned TARABar and TARAChina to be the official ticket sellers. The purchase is done via Taobao and hence one will need a Taobao ID. Tickets are on sale from 29/9 2000CST to 5/10 2000CST and the TARABar ticket link is here. (There are QQGroups for general discussions directly with TARABar and TARAChina but they are all in Chinese.)
Frankly speaking, for international Queen's and especially those who do not understand Chinese, it will be difficult. It is recommended to seek help from a C-Queen's to secure a ticket.
However, I assume if the tickets are not sold out by 5/10, the tickets will be available for purchase via authorised ticketing service providers and hopefully they accept Paypal. (My guess)
And of course, there are people who resell tickets online..
