In 202, following Yuan Shao's death, his subordinates became polarised into two camps because Yuan Shao did not clearly designate one of his sons as his successor. In one camp, Pang Ji, Shen Pei and others supported Yuan Shang and wanted him to be the new Governor of Ji Province. In the other camp, Xin Ping, Guo Tu and others supported Yuan Tan, Yuan Shao's eldest son. Pang Ji and Shen Pei feared that Yuan Tan would harm them if he came to power so they lied that Yuan Shao had named Yuan Shang as his successor on his deathbed. Yuan Tan retreated to Liyang County (黎陽縣; present-day Xun County, Henan) and appointed himself General of Chariots and Cavalry (車騎將軍) there.
