The answer is: Guangwu.
Guangwu (? -208 before), the word uncle, born in (now Taikang, Henan), was the leader of the peasant uprising in the late Qin Dynasty.
In the first year of Qin Ershi (209 BC), in July, the imperial court called Lv Zuo to be stationed in Yuyang, and Chen Sheng and Guangwu were appointed as commanders. They arrived in osawa Township (now the southeast of Su County, Anhui Province), and were delayed by the heavy rain. According to Qin law, if it expires, it will be beheaded. Chen Sheng launched a garrison uprising and put forward the slogan of "Great Chu Xing, Chen". Chen Sheng established himself as a general, took Guangwu as his surname, and called on the masses to go to Fan Qin in the name of Fuxi, the eldest son of Qin Shihuang, and Xiang Yan, the general of Chu.
