袁尚
Yuan Shao was survived by three sons: the eldest son Yuan Tan, the second son Yuan Xi, and the youngest son Yuan Shang. Although it was customary for the eldest son to succeed the father, Yuan Shao had favoured the good-looking Yuan Shang and had arranged for Yuan Tan to be adopted by his elder brother, Yuan Tan's uncle. Since Yuan Shao never formally decided on an heir, the uncertainties regarding the inheritance remained uncertain upon his death, dividing Yuan Shao's camp into two. Among Yuan Shao's advisors, Xin Ping and Guo Tu supported Yuan Tan while Pang Ji and Shen Pei rallied behind Yuan Shang. Although there was a general expectation that the eldest Yuan Tan will succeed his father, the pro-Yuan Shang faction feared reappraisal from Yuan Tan and produced a forged will that proclaimed Yuan Shang as the successor. A resentful Yuan Tan then took his army away to Liyang (黎陽; northwest of present-day Xun County, Henan) by the Yellow River which held the frontier against Cao Cao. Yuan Shang sent a few additional troops with Pang Ji to assist (or spy on) Yuan Tan, but refused his brother's plea when Yuan Tan requested further reinforcements. A furious Yuan Tan killed Pang Ji in response.
