Help with buying tickets for next week's matches in Shanghai

Hi everyone! I'm a foreign student studying in Taiwan, and I'm trying to buy tickets for next week's matches in Shanghai. However, when I enter my Taiwanese number, it doesn’t work. I also tried creating a QQ account, but it flagged my activity as suspicious.

I’m not sure what to do or who to contact to resolve this. Has anyone faced a similar issue or knows how to get around it? Any help would be greatly appreciated!

Thanks!
