There are often inexplicable people on QQ who ask to add friends because they have no anti-harassment, so that others can find and ask to add friends through messages, QQ or other messages.
If these QQ numbers are registered and used for a long time, then these QQ numbers have probably been leaked and made public on some websites. If these numbers are all newly registered applications (as can be seen from grades, icons, etc. ), it may be that existing friends are joking with themselves, or some terminals that publicize bad information maliciously apply for QQ numbers.
