## History

Yuyao is well known for its rich heritage of civilization. The Neolithic Hemudu culture formed in Yuyao about 5,000 B.C. is one of the earliest sites of human civilization on earth. The material and ethical relics revealed large-scale rice plantation and other agricultural activities, hurdle style architecture, paddling and boating and respecting birds and sun.
Yuyao also produced many famous scholars in history—for example, Yan Zi-Ling during the Han dynasty; Yu Fan during the Three Kingdoms period; Yu Xi during the Jin dynasty; Yu Shinan during the Sui and Tang dynasties; and Wang Yangming, Zhu Shunshui, and Huang Zongxi during the Ming dynasty. Wang Yangming and Huang Zongxi were ranked among China's top 10 ideologists. Yuyao was then named as "the Most Famous County" and "the Famous State on Literature". During the Anti-Japanese War, Yuyao was one of China's 19 bases against Japanese invaders and was the center of anti-Japanese bases of eastern Zhejiang province.
