 ## About Yao
 
-Yao's name is derived from the Chinese character **yao (yáo)**, the basic symbol that makes up the Eight Trigrams. The Eight Trigrams is a symbol system created by the ancient god Fuxi after observing and summarizing the laws of nature, which can refer to everything. Yao has two states of yin and yang, like 0 and 1. The transformation of yin and yang of Yao drives the replacement of Eight Trigrams, so as to summarize and record the development law of things.
