Yu Dayou Yu Dayou (1503–1579), courtesy name Zhifu, art name Xujiang, was a Chinese general and martial artist best known for countering the "wokou" pirates along China's southeastern coast during the reign of the Jiajing Emperor in the Ming dynasty.
Erzhu Rong Erzhu Rong (爾朱榮) (493 – November 1, 530), courtesy name Tianbao (天寶), formally Prince Wu of Jin (晉武王), was a general of the Chinese/Xianbei dynasty Northern Wei. He was of Xiongnu ancestry, and after Emperor Xiaoming was killed by his mother Empress Dowager Hu in 528, Erzhu overthrew her and put Emperor Xiaozhuang on the throne, but at the same time slaughtered many imperial officials and took over most of actual power either directly or through associates. He then contributed much to the rebuilding of the Northern Wei state, which had been rendered fractured by agrarian rebellions during Emperor Xiaoming's reign. However, in 530, Emperor Xiaozhuang, believing that Erzhu would eventually usurp the throne, tricked Erzhu into the palace and ambushed him. Subsequently, however, Erzhu's clan members, led by his cousin Erzhu Shilong and nephew Erzhu Zhao, defeated and killed Emperor Xiaozhuang. He was often compared by historians to the Han Dynasty general Dong Zhuo, for his ferocity in battle and for his violence and lack of tact.
