After his accession, Sun Xiu ordered five new counties to be added to Sun Chen's marquisate to appease him, in addition to enfeoffing Sun Chen's brothers as marquises too. However, Sun Chen soon had a fallout with Sun Xiu over a relatively small incident – he brought food and wine to the imperial palace and asked the emperor to dine with him, but the emperor refused. Sun Chen then went to dine with the general Zhang Bu instead and casually remarked that he could replace Sun Xiu easily if he wanted to. Zhang Bu secretly reported Sun Chen's dissatisfaction to Sun Xiu later. Although Sun Xiu continued to pretend to be friendly towards Sun Chen, he began to discreetly raise his guard against Sun Chen. On the other hand, Sun Chen also became worried about his relationship with Sun Xiu, so he requested permission to go to Wuchang (武昌; present-day Ezhou, Hubei) and oversee the defences at the border.
