I can't design a signature, and I can't write it well myself. I only learned to write regular script.

But if you sign these, take a look.

I wrote it in word, and the font was written by myself.

The first two are Ye Genyou's signature and flurry cursive script, the third is Fangzheng Huangcursive script, and the fourth is Xiao Zhuan.

That's all. If you like other fonts, just go down by yourself.

Special design costs money, unless you are lucky and meet an expert, the rest is software. The software basically loads fonts directly. You can write in word, but the software is laid out for you. Word should write its own fonts and change them, but it is more free, and you can choose a variety of fonts (but don't be too greedy, it doesn't matter if you download too many fonts, and installing too many will affect the speed of your computer).
