Since the autumn harvest, when Chen Xi's plan to encroach upon Qingzhou began, Guan and Zhang had been on the border of Qingzhou and Mount Tai, sometimes gathering refugees, sometimes clearing out Yellow Turbans, or helping Zhao Yun reclaim wasteland in Qingzhou.
Guan Yu and Zhang Fei were constantly busy, leading their limited cavalry along the edge of Qingzhou, continuously provoking the Yellow Turbans. Leveraging the superior speed of their cavalry over infantry, they repeatedly evaded the Yellow Turbans' encirclement. Once Guo Jia and Fa Zheng arrived in Qingzhou, besides provoking the enemy and weakening their strength, they strived to lure attacks. Then, they transformed the Yellow Turbans into robust refugees and intensified the efforts in land reclamation.
