Yuan around the new year 555. Chen Xu and Chen Chang were taken to the Western Wei capital Chang'an as honored captives, while Lady Liu and their son Chen Shubao were left at Rangcheng (穰城, in modern Nanyang, Henan). Wang and Chen Baxian initially wanted to make Emperor Yuan's son Xiao Fangzhi the Prince of Jin'an emperor, but after military pressure from Northern Qi, in summer 555, Wang agreed to make Northern Qi's favored candidate Xiao Yuanming (Emperor Yuan's cousin) emperor instead—a decision that Chen disagreed with. In fall 555, he made a surprise attack on Jiankang, killing Wang and deposing Xiao Yuanming, making Xiao Fangzhi emperor instead (as Emperor Jing). In 557, he had Emperor Jing yield the throne to him, establishing Chen Dynasty as its Emperor Wu. Chen Xu's brother Chen Qian was created the Prince of Linchuan, and while Chen Xu was still then detained by Western Wei, Emperor Wu remotely created him the Prince of Shixing, to inherit the title that Emperor Wu posthumously created his father Chen Daotan. Emperor Wu died in 559, and because Chen Chang was still detained at Chang'an as well, Chen Qian took the throne (as Emperor Wen). Because Chen Xu was not available to offer sacrifices to their father Chen Daotan, Emperor Wen created his own son Chen Bomao (陳伯茂) the Prince of Shixing instead, changing (remotely) Chen Xu's title to Prince of Ancheng. In 560, Western Wei's successor state Northern Zhou began to make overtures to Chen, offering to return Chen Xu. In 562, after Emperor Wen gave Northern Zhou the city of Lushan (魯山, in modern Wuhan, Hubei) in exchange, Chen Xu was allowed to return to Chen. Initially, Princess Liu and Chen Shubao were not returned, but after further negotiations by Emperor Wen, they were returned as well. (Chen Xu also welcomed his first wife Lady Qian to his mansion, but as Princess Liu was of an honored birth as the daughter of a Liang princess, she retained the position of his wife, although she gave due respect to Lady Qian) During Emperor Wen's reign Chen Xu quickly became one of his brother Emperor Wen's key subordinates. For example, in spring 562, when the warlord Zhou Di (周迪) rebelled, Emperor Wen initially sent the general Wu Mingche against Zhou, but when Wu was unable to defeat Zhou, Emperor Wen sent Chen Xu to replace Wu.
