許慎
In "Shuowen Jiezi" (c. 58 – 147 AD), China's earliest dictionary, under the entry for Nüwa author Xu Shen describes her as being both the sister and the wife of Fuxi. Nüwa and Fuxi were pictured as having snake-like tails interlocked in an Eastern Han Dynasty mural in the Wuliang Temple in Jiaxiang county, Shandong province.
