In the costume drama "Jun Jiuling", the former princess Jiuling finally returned to the capital by using the identity of Jun Jiuling, and rented a shop in the prosperous place of the capital and established the Nine Ages Hall of the Medical Center. The purpose of Jun Jiuling's doing this was to get acquainted with powerful ministers in the most prosperous parts of the capital and overturn the case for the former emperor. After Jun Jiuling had just returned to the capital, he was discovered by Lu Yunqi, who, like Zhu Zhan, was suspicious of Jun Jiuling's identity. After observing, Lu Yunqi found that Jun Jiuling was very similar to the former Nine Ling Princess, and the stunt used by the Nine Ling Princess when throwing the pot, Jun Jiu Ling would also, Lu Yunqi was very suspicious of Jun Jiu Ling's identity. When Lu Yunqi learned that Jun Jiuling had once been the maid of the Ninth Princess, he still did not give up the investigation of Jun Jiuling.
Lu Yunqi had been sending people to stare at Jun Jiuling, and when Lu Yunqi saw that Jun Jiuling was sad for the crown prince Chu Jiurong, Lu Yunqi questioned Jun Jiuling's identity, and Jun Jiuling did not admit his identity to Lu Yunqi in order to keep the people of Jiuling Hall. Jun Jiuling had always had a grudge against Lu Yunqi, and if it were not for Lu Yunqi, his father and emperor would not have been killed by Chu Rang. Lu Yunqi could have told the emperor the news of Chu Rang's rebellion, but Lu Yunqi did not do so, and Lu Yunqi betrayed the former emperor and the Ninth Princess for his own selfish desires.
After Jun Jiuling returned to the capital, he was alone and helpless, and could only find the Twelve Emperor Uncles who had once loved him, and confessed his identity to the Twelve Emperors. When Uncle Twelve emperors said a code word between the two people at Jun Jiuling, uncle twelve emperors believed that Jun Jiuling was a former princess. With the help of the Twelve Emperors, Jun Jiuling also successfully overthrew Chu Rang's rule, and allowed his younger brother Chu Jiurong to successfully ascend the throne and become the new emperor. Uncle Twelve paid a lot for Jun Jiuling's plan, and Jun Jiuling learned that Uncle Twelve had been working against Chu Rang in the middle of the dynasty, and only then did he find Uncle Twelve Emperor, and the reason why Jun Jiuling confessed his identity to Uncle Twelve Emperor was that he hoped that Uncle Twelve Emperor could remember his old feelings and help him defeat Chu Rang. Jun Jiuling relied on the favor of the Twelve Emperors and believed that the Twelve Emperors would definitely stand on his side.
