Xu Changjin did exist in history. She is an unprecedented female doctor in North Korea. She was recorded in A Record of Zhong Zong, and the word "Da" was added before her name, so she was called "Da Changjin".

According to Records of the Korean Dynasty-Records of Zhongzong, Xu Changjin was the first female doctor in Korean history. There is not much pen and ink about this legendary figure in the history books, only a few words are recorded one after another, mentioning that Zhongzong trusted Dae Jang Geum very much, completely diagnosed her and gave her a lot of rewards. It's a pity that no matter how good a medical officer is, he can't resist the law of birth, illness and death.

There is a book called "Notes of Li North Korea's National Medical Officer", which is for Chang Jin.

Described in detail, she used about 250 words to mention her research in acupuncture and dietotherapy: "The medical woman is a woman with a long life, and her surname is Wu, so people can't find out at present. In the eighteenth year of the eleventh Emperor Zhongzong, she was named as the King Dae Jang Geum ... In her dragon body, before the medical treatment, Zhongzong allowed her to believe that the name of non-Jang Geum was also recorded. It's called diet therapy. Say it. It is said that she was punished after the death of Zhongzong and was exiled to China. Later, the queen regained her identity and died in Mingzong 1566.

Changjin is a unique strange girl in Korean history. The medical skills are superb, and the medicated diet and supplements made are also delicious. Until today, Changjin's medicated diet and acupuncture secret recipe are still widely studied and promoted in Korean traditional Chinese medicine circles.

But what is certain is that Koreans are exaggerating, so are business and medicine, and so are Dae Jang Geum. I hope it helps to find it online.
