Zhang Miao
When Lü Bu left Yuan Shao to join Zhang Yang in Henei (河內; in present-day Henan), he passed by Chenliu and met Zhang Miao. Zhang Miao treated him generously and made a pledge of friendship with him when he saw him off. Yuan Shao was angry when he heard that Zhang Miao had befriended Lü Bu. Zhang Miao also feared that Cao Cao might ally with Yuan Shao to attack him so he felt very uncomfortable. Besides, his jurisdiction, Chenliu, was in Yan Province, which was under Cao Cao's control.
