There are many personal signatures I like, such as the one I use now. White tea, nothing else, I'm waiting for the wind, waiting for you. I think this sentence is beautiful, so I will take it as my signature. There are many other sentences that you can use as your signature, for example. You pass by me unintentionally like the wind, but you set off a storm in my world. I like these sentences very much. I have done it with my signature.
