 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.
