Kong Rong
Around 189, Zhang Rao (張饒) led some 200,000 Yellow Turban remnants to ravage Qing Province. He defeated imperial forces under Kong Rong, the Han-appointed Chancellor of Beihai State (around present-day Weifang, Shandong) in Qing Province. Later, Kong Rong was besieged in Duchang County (都昌縣; present-day Changyi, Shandong) by thousands of Yellow Turban rebels led by Guan Hai (管亥). Taishi Ci, then a military officer under Kong Rong, managed to break out of the siege and seek help from Liu Bei, who was then the Chancellor of the nearby Pingyuan State. Liu Bei brought along 3,000 troops to attack Guan Hai and succeeded in saving Kong Rong.
