Цзян Вэй
At that moment, Jiang Wei was patrolling the outskirts with his commanding officer Ma Zun (馬遵), the Administrator of Tianshui Commandery. Afraid that Jiang Wei might be colluding with the Shu army, Ma Zun fled secretly at night to Shanggui County (上邽縣; in present-day Tianshui, Gansu). When Jiang Wei discovered this, it was already too late and on returning to Shanggui County, the defenders refused to open the gates for him. As a result, Jiang Wei defected to the Shu side along with his colleagues Liang Xu (梁緒), Yin Shang (尹賞), and Liang Qian (梁虔).
