Zhuge Dan
Sima Zhao wanted to eliminate the remaining loyalists to the state, so he heeded Jia Chong's advice to force Zhuge Dan to rebel. Zhuge Dan received an imperial decree to report to the Wei court and assume the post of Excellency of Works. However, Zhuge Dan became afraid after receiving the decree, so he killed Yue Lin, the Inspector of Yang Province, and rebelled against Sima Zhao. He sent his Chief Clerk Wu Gang (吳綱) to Eastern Wu with his son Zhuge Jing as a hostage, asking for reinforcements from Wu.
