Han Xiaozhu expressed her gratitude to Jin-hee Ji, because during the filming, Jin-hee Ji comforted her whenever she felt tired. Han Xiaozhu said that when filming Yi Tong, he always took chocolate with him and used it as a preventive medicine. 20 10 On September 3rd, Yi Tong announced to stop filming because MBC TV failed to reach an agreement with the Korean Artists' Union. On September 6th, due to the agreement between the production company and the Korean Artists Union, the Yi Tong crew resumed normal shooting. In order to shoot the MBC TV series Yi Tong, Han Xiaozhu also specially studied Qin Hai's performance. In order to play the role of the first19th generation Wang Suzong of the Korean dynasty, Jin-hee Ji also went to the gym to exercise. Yi Tong was originally planned to air 50 episodes, but in order to avoid an anticlimactic ending due to insufficient episodes, the play was extended to air 10 episodes. Ha-seon Park, who plays Empress Renxian in the play, was reprimanded by the director many times in the early stage of filming, so she was so depressed that she didn't even dare to read the online comments on the play. Historical mistake Cui Xiaoyuan, the father of Cui Shi, paid homage to General Xuanlue before his death. After Yingzu acceded to the throne, he posthumously awarded Dr. Lu Chong and made a big proposal. Therefore, Cui Xiaoyuan is not untouchable. In the second year of Su Zong (1676), Shu will be a concubine. At the age of six, she was neither a maid of the Conservatory nor a supervisor of her wife. In the ninth year of Su Zong (1683), when he entered the palace again, Wang Jin had died. The harem platter was indeed given by the queen, but it was impossible for the queen to distribute it herself. Generally speaking, it should be read from the palace to the palace, to the concubines or the Shang palace, and the conferring ceremony in the play is unreasonable. It's a mistake for all the actresses in the play not to add parallelism. The addition of parallelism was cancelled in the thirty-third year of Yingzu (1757). After six years in history, concubines with official titles cannot leave the palace until the king dies, unless they are abolished. After the death of Empress Renxian, Su Zong issued a decree that concubines in the harem should not become queens, so Su Zong could not consider making Cui Shi a queen. Empress Renyuan did not accept Yan Jun as her adopted son. After Zhang's death, except for Empress Renyuan's entry into the palace, the whole plot was fictitious. There is no Zhang Wulie in the official history, and what she did can't happen naturally. Cui Shu left the palace to live a private life before his death.
