乃遣周万户等往招降之。唆都趋建宁，遇宋兵于崇安，军容甚盛。
Just as he was preparing to set off, the garrison of Xinyang came to ask for help, claiming that the remnants of the Song Dynasty in Shaowu were gathering and waiting for an opportunity to attack Xinyang. So Du sent Zhou Wan to surrender the Song army in Shaowu, and he went to Jianning.
