Lü Fan
In late 222, Cao Pi ordered his general Cao Xiu to lead the Wei armies to attack Dongkou County. In response to the invasion, Xu Sheng, along with Lü Fan and Quan Cong led Sun Quan's forces across the river to defend Dongkou. However, they encountered a storm and many of their troops and ships were lost. Sun Quan's generals were browbeaten because they had lost about half of their ships in the storm, but were overjoyed when they heard of the arrival of He Qi, who reached Dongkou behind schedule and was not affected by the disaster. Coincidentally, He Qi was obsessed with luxuries so his ships were finely decorated and his weapons were of top quality. Cao Xiu was shocked when he witnessed the grandeur display of He Qi's refulgent navy so he paused the attack and withdrew. Xu Sheng managed to gather his surviving troops and form a defence line along the shore. A naval battle ensued, during which Cao Xiu targeted Lü Fan while sending his subordinates to attack Xu Sheng. Xu Sheng was outnumbered but he managed to hold his position. Both sides eventually withdrew their forces. Xu Sheng was subsequently promoted to General Who Stabilises the East () and elevated from the status of a village marquis to a county marquis under the title "Marquis of Wuhu" ().
