Signing on blank paper is generally considered as confirmation and authorization in law. Signing on blank paper is easy to be stolen by others and bears unnecessary legal responsibilities. For example, if you put an iou in front of your signature or provide a guarantee, you can bear the loss for nothing. So don't leave blank signature paper in other people's hands.

I believe everyone has a favorite star in their heart, right? Generally, fans will silently pay attention to the works of their idols, and fans who are a little more intense will go back to various venues or airports to see their idols with their own eyes, but these are a few. After all, there is still a great distance between the lives of stars and ordinary people.

However, although the distance is far away, you can't stop it when fate comes. I wonder if you have ever met a star. When you meet a star, there is always a "standard ceremony", taking photos first and then signing.

I believe anyone can sign it if you want. After all, having a signature is equivalent to having a sign of meeting an idol, which is also a very happy thing. But for stars, autographs are very particular, and names cannot be signed casually.

The last thing that can be signed is white paper, because the signature represents the identity, which will be used when signing many contracts. If you sign it on white paper, it is likely to be used by criminals. Such things often happen to ordinary people. As a star, of course you pay great attention to this. Even if you are unconscious, the company will remind artists. It's not that stars refuse to sign on white paper, but the world is too dangerous.
