Someone else said the new Qq number.

This is because someone used this QQ before and Tencent took it back, so the record will not be deleted. Tencent will now take back 9 digits and QQ numbers that have not been logged in in the next 3 months, and only 8 digits and the previous 8 digits will not be taken back. Tencent will empty all its friends when it takes them back, but he can't empty other people's friends, so someone will give you a comment. Comments were made by friends of your former owner.
