What I designed was to write the yin bigger and draw the jade under the yin in cursive script. But the "gang" should wrap both "Sun" and "Jade". It would be cool if a man signed it. If it's a woman, it has to be beautifully written. I didn't attach what I wrote. Of course, the signature should be scribbled, and it is best to scribble the word "Yin" as much as possible. Yu Sun in the lower right corner can be brushed aside (according to Tian Zi, it accounts for two-thirds of the grid). You can write one stroke or two strokes. Yin can write later or first. I've written it. It looks better in the back, but don't write too high. You can write it wider. "Hmm" is best written on the left. "You" is written under "You". Write yin higher. This looks very good.
