Yao (yáo) is the same as Yao in ancient times. It means that the mountain is high or has grown high.
You can choose "Xin" (Zhang Xinyao), which means borrowing soil to generate gold.
Although the word "Yao" is rustic in appearance, its core is towering, which can tell the child the meaning of the name and warn him to use the word "Yao" in a down-to-earth way, hoping that his goal is high.
