1. Email addresses may be rejected depending on the email service or region you are using.
2. The reason for registration must basically be written in Chinese.
The site operator sees the reason for registration and decides whether it is acceptable.
3. The reason for registration must be exactly 30 characters. Or it must be at least 30 characters long.
4. Gender is from the top, secret, male, female.
5. It is much more advantageous to have a QQ account.
But to get an account you need a Chinese phone number, so it's difficult for people who don't live in China.
Good luck.
