Zu Mao

Zu Mao (rōmaji: So Mo) is an officer who served under Sun Jian. He was one of the first four generals to fight alongside his lord to defeat Dong Zhuo.

Historical Information
When Sun Jian's army attacked Liangdong, Xu Rong was sent by Dong Zhuo to defend the area. Xu Rong led a quick surprise attack and Sun Jian was forced to flee. However, Sun Jian was unable to shake off pursuit, and Zu Mao exchanged headgear with Sun Jian. The soldiers under Xu Rong chased after Zu Mao, allowing Sun Jian to escape. Zu Mao later hung Sun Jian's headgear onto a half-burnt pillar, and hid himself in the tall grasses nearby. The enemies surrounded the pillar and approached cautiously till they realized they had been fooled, whereupon they retreated. Zu Mao's fate henceforth was not documented.

Romance of the Three Kingdoms
In the novel, the same incident happened in Sishui Pass, and it was Hua Xiong that led the pursuit. When Hua Xiong closed in on the pillar, Zu Mao came out of his hiding to attack Hua Xiong, but was cut down by the latter. He was known for wielding a pair of swords.
