My method is: Memo, add an expression or number at the beginning, then wrap the line and add two spaces until you want to write the final text until the editable text 0 is displayed.

The new personality signature contains characters that are not allowed to be entered by the system, and will be blocked, so the personality signature cannot be updated, and the old one is always displayed!

The other party has set the permission of the circle of friends, but you just can't see the information of the circle of friends. The signature of the other party can still be seen, because you are still friends, and the information of the other party can still be displayed on your mobile phone, but the information of friends circle can't be displayed. You can also set synchronization with qq.
