I will give you one. I don't know if you like it or not. Write it down after downloading. It may be awkward at first. The more you write, the more familiar you are, the more accustomed you are, and the more you read, the richer your content is. What can you see? Look up, look left, look right, look before, look after, look before, look after, and you will understand in the end. This personalized signature is elegant enough that others can't sign it.
