Shizu ordered Boyan to attack Song. The courtiers believed that the Song army was mostly concentrated in Liang Huai. When they heard that the army was about to cross the river, they would definitely move the Liang Huai army to defend against it. So they ordered the Right Guard Commander Tu Manda to lead 20,000 light and elite soldiers to attack Huaian and Junxiang followed as the commander of the Mongolian Han army.
