위연
Wei Yan's death was explained in political terms in "Injustice to Wei Yan" (), a neoteric article by Zhu Ziyan, a history professor from Shanghai University. In the article, Zhu wrote that Zhuge Liang personally appointed Jiang Wan, Fei Yi and Jiang Wei to be his successors, but Wei Yan's appointments and contributions were greater than those of any of them at the time. Zhuge Liang ostracised Wei Yan and cracked down on him because he wanted to eliminate Wei Yan as a possible obstacle to his appointed successors.
