In 557, Chen Baxian seized the throne and established the Chen Dynasty as its Emperor Wu. While Chen Xu was then still detained at Chang'an, he remotely created Chen Xu the Prince of Shixing. Subsequently, when Emperor Wu died in 559, because Chen Baxian's son Chen Chang was still detained at Chang'an as well, Chen Xu's brother Chen Qian succeeded Emperor Wu (as Emperor Wen). In 562, following negotiations, Western Wei's successor state Northern Zhou agreed to allow Chen Xu to return to Chen. Later that year, after further negotiations, Lady Liu and Chen Shubao were allowed to return to Chen as well. As Chen Xu then carried the title of Prince of Ancheng, she carried the title of Princess of Ancheng.
