諸葛誕
In the winter of 256, Eastern Wu sent troops to attack Xuye (徐堨). While Zhuge Dan was able to handle it, he requested 100,000 more troops from the Wei imperial court, and planned to build castles to defend the region. Sima Zhao felt that Zhuge Dan was behaving suspiciously, so he sent his close aide Jia Chong to meet Zhuge Dan and assess whether he was loyal to the Wei emperor Cao Mao or to Sima Zhao. After Jia Chong reported that Zhuge Dan supported the emperor, Sima Zhao sent him an imperial order in the emperor's name, instructing him to return to Luoyang to serve as Minister of Works. (While this appeared to be a promotion for Zhuge Dan, it was actually to remove him from his military command in Shouchun and recall him back to Luoyang, where he would be under Sima Zhao's watch.)
