Yao is a robust tiger with unique facial markings, and he appears to be in his late 20's to early 30's. He adorns navy blue overalls and a corresponding cap, along with a gray collared shirt that has its sleeves rolled up. While working, he carries a tool bag on his belt, but he removes it in more relaxed settings.

It is worth noting that Yao has a subtle accent that, as Samuel has pointed out, lends his words a melodious quality. A charming attribute that adds to his overall appeal.
