In 195, Yuan Shu, who had the intention of usurping the Han throne and declaring himself emperor, ordered his forces to start conquering nearby commanderies and counties. Liu Yao sent his subordinates Fan Neng () and Zhang Ying () to station troops near the riverbank to guard against Yuan Shu's advances. As Wu Jing and Sun Ben previously had served under Yuan Shu, Liu Yao distrusted them and forced them to leave. Yuan Shu appointed himself as the Inspector of Yang Province, and allied with Wu Jing and Sun Ben to attack Liu Yao. Fan Neng and Zhang Ying managed to hold their positions against enemy attacks for several days.
