 In 562, when the warlord Zhou Di (), who controlled parts of modern Jiangxi, rebelled, Wu was made the governor of Jiang Province (江州, roughly modern Jiujiang), to command the army against Zhou.However, the strict Wu was unable to get his subordinate generals to obey his orders, and Emperor Wen subsequently sent his brother Chen Xu the Prince of Ancheng to replace Wu.In 564, Emperor Wen made Wu the governor of Wuxing Commandery (吳興, roughly modern Huzhou, Zhejiang) -- an apparent demotion, but as Emperor Wen pointed out, actually an important position because Wuxing was the imperial Chen clan's home commandery.
