Historical Information
Ma Zun was the nameless Prefect of Tianshui in Jiang Wei's scroll for Record of the Three Kingdoms. His name is given in the Weilue.

In 228, Zhuge Liang was approaching Qishan on his northern campaign. Ma Zun decided to counter the threat by sending out troops for border patrol, ordering Liang Xu, Yin Shang, Liang Qian, and Jiang Wei out. As they were out, Ma Zun heard other prefectures were in the midst of defecting, and he began to doubt the loyalty of his scouts. During the night, he fled his post to a castle in the upper Gui County. His actions were noticed by the stranded scouts, whom tried to re-enter the castle gate. Refused at the castle and at the Ji District, they were soon surrounded by Zhuge Liang's troops and decided to surrender.

Ma Zun's whereabouts after the incident aren't clearly indicated. However, Zhang Ji's scrolls indicate that Wei's Prefect of Tianshui and Prefect of Nan'an abandoned their posts and tried to flee to the east. Whilst on the run, they ran into the Prefect of Longxi County, You Chu. You Chu was currently cut off from communications with the main command so he had to deal with the two runaways by himself. Upon hearing that they fled from Zhuge Liang, he chided them for abandoning the people within their posts and the land's trust; his words had them weep with shame. He gave them the offer to redeem themselves by joining his defense against the incoming Shu army. You Chu would only allow the two prefects to surrender to Shu in the event their position fell. After ten days of fighting, Zhuge Liang eventually withdrew from the area. You Chu was recorded as the lone commander who remained at the post.

Since the two prefects are not mentioned thereafter, there has been speculation that they could have left the area with Shu's army. Others argue that the prefects were too cowardly to even think of fighting and fled once more to an unknown location.
