Lü Fan
The "Jiang Biao Zhuan" recorded that Sun Kuang served under his second brother, Sun Quan (Sun Ce's successor), as General of the Household Who Solidifies Martial Might (定武中郎將). He fought in the Wu army at the Battle of Dongkou of 222–223 against Wei invading forces commanded by Cao Xiu. During the battle, he ordered the Wu general Lü Fan to set fire, but accidentally destroyed a large portion of the Wu army's supplies, resulting in a shortage. Lü Fan immediately sent Sun Kuang back to the Wu capital. Sun Quan was furious with his younger brother and he punished his brother by forcing him to change his family name to "Ding" (丁) and placing him under permanent house arrest.
