This contract has legal effect. Based on the principle of voluntary negotiation, it is generally agreed to re-sign, right? Hmm. How interesting

It's your right to sign at will. As long as it doesn't affect the exercise of others' rights, you can teach others to know you if they don't know you. This is voluntary, not prohibited by law.

Generally, others won't let you re-sign. You can refuse if you can recognize your name. Re-signing is also effective, because the handwriting is yours and can be recognized.

In short, I have the right to choose my own signature method, even if others don't know it. However, it doesn't matter how you sign it, even if you don't know each other. As long as it is your own name, as long as it does not hinder others from exercising their rights, this is called prohibiting abuse of rights. If others don't know you, you can show that many people don't know you, which is related to the rights of others. You must re-sign.
