However, his strategy turned out to be faulty—as he was initially targeting Shouchun (壽春, in modern Lu'an, Anhui) but, on his way, changed his mind and attack Hefei instead, despite the fact that Hefei's defenses were strong and intended to withstand major Eastern Wu attacks.
Sun Xiu sent two separate forces, one attacking Shouchun and one heading toward Hanzhong to try to alleviate pressures on Shu Han, but neither was at all successful, and Shu Han's capital Chengdu and its emperor Liu Shan surrendered later that year without having received major help from Eastern Wu.
Chu lost the initiative and could only sustain local guerrilla-style resistance until it too was fully conquered with the destruction of Shouchun and the death of its last leader, Lord Changping of Chu, in 223 BC.
