Lu Su
The allied forces of Sun Quan and Liu Bei launched fire attacks on 800,000 soldiers of the troops of Cao Cao, in the red cliff (today's Chibi city, Hubei province), thus forming the tripartite confrontation of Cao Wei (220–265), Shu Han (221–263), and Eastern Wu (222–280) from then on. Later, Sun Quan of Eastern Wu dispatched Lu Su to lead troops to defend Baqiu (; today's Yueyang), so as to scramble for Jingzhou with Liu Bei. Lu Su built Yuejun Tower () on the top of the city wall by Dongting Lake, to train and review the navy. Yuejun Tower was the former Yueyang Tower. Under the Yueyang Gate, and by Dongting Lake, was the site of the Call-officers-roll Platform (), where Lu Su reviewed the navy of Eastern Wu at that time.
