2. Yao (yáo) is tall. This word is not commonly used (so I can't type it with intelligent pinyin input method, and I think this word is relatively uncommon, so it is not appropriate to use it as a name. At least I won't choose a word that is difficult to recognize as the child's name. What I occasionally see is either used as a store name or a name. "Tu" also includes Tu, Gui and Yao. The first time I saw "Yao", I expected that Wen guessed that the word "Yao" should mean "Tuduo" (because Xin, Sen, Miao and Yan basically mean "more gold, more wood, more water and more fire", so I think Xin, Sen, Miao and Yan should belong to the recognition word), and I found that it means "high" when I looked it up in the dictionary. Yao should be the most rustic Chinese character.
