The page looks entirely in Chinese. Do we need Google Translate all the time for this CTF?

For CTF web page and challenges themselves, it's ok if you don't kown the Chinese.
It's the second year we hold this competition, there are still many shortcomings. Next year we will absolutely develop a English version web page for the international ctfers.
Please feel free to contact us : : ) if you have any questions.

I don't get why the organizers would use a QQ group when US phones aren't even allowed to create a QQ account. At least choose Wechat if you're going to use a Chinese platform
