## History

Sihui was initially established during the Qin dynasty (221 BC—207 BC), some historians suggested Sihui first appeared during the Western Han dynasty (206 BC—8 AD), and it is one of the four most ancient counties in Guangdong province (the other three counties are Panyu county, Jieyang county and Longchuan county). Under the Qing, Sihui County made up part of the commandery of Zhaoqing. As with much of the surrounding countryside, Sihui was a source for many members of the Chinese diaspora during the late Qing.
