In the first year of Guangwu (1897), 12 10, Li Xi proclaimed himself emperor and changed his name to "Korean Empire". Eight days later, Yan Shanggong gave birth to a son for British Prince Li Yin. Two days later, Yan Shanggong was made a nobleman. With the birth of her son, Yan's ambition is getting bigger and bigger. Taking advantage of the favor of Emperor Gaozong, she was prepared to follow the example of Princess Min and try to interfere in political affairs. According to historical records: "Yan's specialty is the art of blessing, and his family is rich." He intervened in politics and held many official positions. His Yinya family has a rich official title, and both the ruling and the opposition have power. " In the third year of Guangwu (1899), Japanese ambassador to North Korea Masuo Kato also reported to his government: "At present, Yan Guiren is quite authoritarian in the palace, and he is often asked to appoint ministers and appoint and dismiss other officials. Therefore, if government ministers want to expand their power, they must first entrust Yan Guiren. " At that time, not only Zhao, Yin Rongshan and other court officials were closely related to the Yanshi family, but also Yan, Yan, Jin Yongzhen and other Yanshi consorts were successively appointed to important positions.

However, if Yan wants to interfere in state affairs, he must first get a birthright. Although she actually became the queen of Emperor Gaozong's harem and began to interfere in politics, she did not want to be a concubine and was determined to covet the throne of the main palace of the Korean Empire. From the third year of Guangwu (1899), some people suggested that she be the queen, and some people, such as Jiang Zan and Jin Sizhe, requested to be strict wives. In August of the fourth year of Guangwu (1900), the son of Yan family was made king of England, and then Yan Guiren was named Chunyi. In September of the 5th year of Guangwu (190 1), Suiyuanpu, the birth mother of Chunzu in North Korea, was given the title of Suiyuan. Later, Yin Rongshan, the confidant of Yan family, took the opportunity to advise Gao Zong that since Suiyuan was upgraded to Suiyuan, Yan Yuan should also be named Suiyuan. Ye Zhao called it: "Today, I am a strict family, and I have been in the royal family for a long time. I have the reputation of being a clean chapter. I am a prince, but my rank is still low. I am afraid I owe it to my son. " The axe king longed to be a princess, so as to determine her name and allow her to get married. "So Guangwu five years (190 1 year) 10 month, Yan was promoted to Chunfei, and the palace number was" Castle Peak Palace ". Being a princess is just a springboard for Yan's family, and its ultimate goal is to become the queen of the Korean Empire. So, at her instigation, some Confucian scholars and ministers launched a "promotion and evacuation movement", which caused a huge storm in South Korea and even involved South Korea's diplomacy, and became an important event on the political stage of the Korean Empire.

In June of the sixth year of Guangwu (1902), former judges Han Gengen and Shen each led hundreds of gentry and Zhang Fu to retreat and asked Yan Fei to be the queen. Later, more than 400 officials and gentry joined hands to retire, and eight Confucian scholars, including Li, set up a retirement hall for ten thousand people, all demanding the promotion of Yan Fei. In June and July of the following year, there were others. Feng Shanjun, Zhao Dongwan and others led more than 13 gentlemen to visit, so please make Yan's family queen. Their reason is that if there is no "queen", it will lose the face of the country. In layman's terms, they advocate that the country should have a first lady. Among them, Li Genze, the confidant of the new Yanfei, pushed the hardest in the dark. "At that time, the whole country was crazy and asked nothing else." South Korean political circles launched a fierce struggle around Yan Fei's promotion. At that time, pro-Russian and pro-American factions in South Korea and Min Yongjun, Min Yonghuan and Min Shao Yong of the Min family in Li Xing resolutely opposed Yan Fei's promotion. In order to protect the interests of Crown Prince Li Mao, they quoted the story of Zhang Xipin in the Su Zong period of Korea, and pointed out that it was the law of ancestors that the harem could not be admitted to the official position. Pro-Russian giant Li even ridiculed Yan Fei as Tang and Yang Guifei. In addition to her promotion, Yan Fei also tried to let her son, Crown Prince Li Yin, replace the then Crown Prince Li Mao. As Li Yong was sickly and infertile, Yan Fei secretly promoted this conspiracy while striving to be the queen. Therefore, she began to actively unite with Japan. In the fourth year of Guangwu (1900), she sent a cloud to Japan to prevent the righteous prince Li Yong and the grandson of Courtyard Jun from returning to China on the condition that Japan and South Korea reached a national defense alliance. However, Yan Fei's various plots failed, mainly because of Gao Zong's caution. Although Emperor Gaozong preferred Yan Fei, he still missed Empress Mingcheng in his heart, and "when the princess was in office, the prince should be a vassal and call him Niang, so he couldn't bear to decide." Yan Fei's alliance with Japan also violated the emperor's policy of neutral diplomacy, which was not allowed by the emperor, and Jiang Xihao, the emperor's confidant eunuch, also opposed Yan Fei's promotion. Even Princess Yan herself was obviously surprised by this promotion. According to historical records, "Yan is a special pet, but she is smart and tolerant. When she hears the seal, she will be surprised:' I will die later!'" "Don't allow ... every time the prince enters the palace, he sharply asks,' Do you want a queen?' Fei Xun replied,' How dare a villain!' "

In this case, Emperor Gaozong chose to compromise, that is, to promote Princess Yan Chunfei as the imperial concubine instead of the queen. In the seventh year of Guangwu (1903) 65438+February 25th, Princess Yan Chunfei was officially conferred as the imperial concubine, and was congratulated by hundreds of officials. After her promotion, the storm came to an end. The storm of Yan Fei's promotion had a great influence on Korean politics at that time, which intensified the factional opposition within the Korean Empire. At this time, the opposition between Japan and Russia in South Korea is intensifying, and South Korea urgently needs to achieve neutrality. However, the South Korean government is arguing endlessly about the status of concubines in the harem, which prevents it from carrying out any active foreign policy and delays the opportunity of neutral diplomacy. In addition, Yan Fei did not hesitate to collude with the Japanese to engage in South Korea for her own power and status. Japan also used Yan Fei to infiltrate, pretending to be Yan Fei's distant niece, and Pei Zhenzi (the wife of Xuan Yingyun), a female spy kept by her, was placed in the Korean court to carry out various conspiracy activities. Therefore, the turmoil after Yan Fei's promotion caused great harm to the Korean Empire.
