Cui Hao
Later in 422, after Liu Yu's death, Emperor Mingyuan decided to launch a major attack on Liu Song. Cui Hao opposed this, believing that Liu Song could not be conquered. However, this was one instance that Cui only appeared to be partially correct, as the armies under Emperor Mingyuan were able to capture Liu Song's northern regions, directly south of the Yellow River, although Emperor Mingyuan's original lofty goal of destroying Liu Song was nowhere close to being met.
