富县
In 211, Liu Bei led an army from Jing Province into Yi Province on the pretext of helping Yi Province's governor, Liu Zhang, counter an invasion from the warlord Zhang Lu in Hanzhong Commandery. Zhuge Liang remained behind to guard Jing Province while Pang Tong followed Liu Bei to Yi Province. Liu Zhang received Liu Bei at Fu County (涪縣; present-day Mianyang, Sichuan). Pang Tong urged Liu Bei to use the opportunity to capture Liu Zhang and force him to hand over Yi Province, but Liu Bei refused because he was new to Yi Province and had not established a strong foundation there yet. Liu Zhang later returned to Yi Province's capital, Chengdu.
