Usually it’s a collection of characters. You can use Baidu Yiha Calligraphy Dictionary. You can find the characters on general celebrity names. There are online ones. Find some fonts or vector images you want, cut them out and spell them out. Just do it together. Of course, if you are a master, you can write it yourself. If you don't choose a little bit, you can use font software and find a cursive script writer to type it yourself.
