I didn’t know ICANN request email address verification, I thought freedom everywhere outside China, but looks like it’s not. :-)
My domain was suspended due to that ICANN policy, and my QQ mailbox unable to recieve verification email from ICANN, what a unfreedom country it is! Finally I have to change my domain register mailbox to Gmail to get the email.
