The Jin left aided by the Jin center continued to maintain their positions against the Chu center. Though the Jin centre was temporarily disordered by an intense whirlwind, it was effective in preventing the Chu center from supporting its left wing. As the Chu left advanced, it was caught in the flank by Duke Wen's bodyguards, composed of the sons of noble clansmen and sons of his close followers and thus flanked by the Jin central army. Meanwhile, the entire force of the Jin right wing completed its recircling and was supported on its right by Luan Zhi's chariots to join the assault. The Chu left was completely destroyed. Seeing both his wings enveloped, Ziyu ordered a general retreat.
