Zhang Aibin (), the concubine of Emperor Suzong of Joseon, whose real name was Zhang Yuzhen. Because she was awarded the title of first-class "Jubilee", she was often called Jubilee Zhang () in history books, and was later shortened to Zhang Aibin.

Zhang Yuzhen was born in Rentong, and her ancestor was Zhang Anshi, a famous minister of Goryeo. After the founding of the Joseon Dynasty, Taizu Li Chenggui wrote many times to invite Zhang Anshi to join the court to assist the government, but he was declined. Finally, he sent his son Zhang Zhongyang to serve in the new dynasty and live in Zuoyin, Seoul Prefecture. The Rentong family to which Zhang Xibin belonged belonged to the middle class in later generations, and most of them were engaged in occupations such as Chinese translators and painters. Zhang Xibin's father, Zhang Jiong (1623~1669), was a translator during his lifetime and "served as deputy minister in the Translation Institute". Zhang Xuan, Zhang Xuan's cousin, was also a translator. He often traveled to the Qing Dynasty as envoys and made huge profits through trade. He was called "the richest man in the country". Zhang Jiong first married his wife, Gao, and gave birth to a son, Zhang Xizhen, who died young. Later, he married his stepmother, Yin, and gave birth to a son and two daughters. The son was Zhang Xizai, Zhang Xibi's brother, and the second daughter was Zhang Yuzhen. "Records of the Joseon Dynasty" records that in the sixth year of Suzong's reign (1680), Zhang Yuzhen's cousin Zhang Xuan was involved in the "Sanfu Incident" and was "sent a far-off wife." The Zhang family was also implicated and their homes were ransacked. Zhang Yuzhen's If you don't enter the palace, you will become a concubine. After Zhang entered the palace, she was appreciated by Suzong's great-grandmother, Princess Zhao (Queen Zhuanglie). And because of his outstanding appearance and temperament, he was favored and favored by Emperor Suzong of North Korea. When King Suzong's first wife, Queen Renjing, was alive, she "had a strict nature, and the emperor was very afraid of her. She would not dare to have anything personal with the palace people in the rest of her life." After the death of Queen Renjing, Suzong began to visit Zhang Yuzhen. However, this move aroused strong dissatisfaction with Queen Sujong's mother, Princess Kim (Queen Myeongseong). Queen Myeongseong ordered Jang Yuzhen to be expelled from the palace, and immediately after the mourning period of Queen Inkyeong, she chose Min, the daughter of Bingcao Banshu Min Weizhong, as her stepmother. (That is Queen Inhyun). After Zhang Yuzhen was expelled from the palace, she was adopted into the family of Li Cheng, the Chongshan Lord of the royal family (the son of Injo's deposed noble Zhao family).

The lineage of King Suzong was passed down to only three generations, and the population was originally small. However, Queen Inhyun was childless for a long time after entering the palace, which put her in an embarrassing situation. Queen Inhyun knew about the old affair between Suzong and Zhang Yuzhen. In order to make the royal family more popular, she took the initiative to propose to Suzong to take Zhang Yuzhen back to the palace. However, she gave up due to the opposition of Queen Myeongseong. In the ninth year of Suzong (1683), Mingsheng After the queen died, Queen Renxian once again asked Suzong to take Zhang Yuzhen into the palace, so Zhang Yuzhen was able to return to the palace. After Zhang Yuzhen entered the palace for the second time, she was even more favored than before. She also relied on favors and became arrogant and increasingly domineering. Her relationship with Queen Inxian was tense. According to historical records: "Any envoy in the inner palace (Queen Inxian) was disrespectful. In order to contain her, Queen Inxian attracted the Jin family, a relative of Jin Shouheng, an important Western minister, into the palace (later Ningbin Jin family) to share her favor, but it seemed to have no effect.

On December 10, the twelfth year of Suzong's reign (1686), Zhang Yuzhen was granted the title of Shuyuan, and was soon promoted to Zhaoyi. From then on, Zhang Yuzhen began to cultivate her power, and with her help, she promoted her mother Yin's concubine Zhao Shixi to the right-hand political position. Her brother Zhang Xizai, close confidant Dongpingjun Li Hang (son of Lord Chongshan), etc. also began to form a party for private gain.

On October 28, the 14th year of Suzong's reign (1688), Zhang Yuzhen gave birth to Suzong's first son Li Yun (later Jingzong of Joseon) at Juishantang in Changqing Palace. Overjoyed. However, many people were very dissatisfied with Zhang Yuzhen. When Zhang Yuzhen's mother Yin came to the palace to visit her after giving birth, her sedan chair was burned by Li Yishou, the Ping Ping of the Si Xian Mansion, and ordered the forbidden officials and Zaoli of the Si Xian Mansion to arrest the bearer. Emperor Suzong heard that Furious, he ordered Li Yishou to be dismissed from his post, and the forbidden officials and Zaoli of Si Xian Mansion who were involved in the matter were killed with a cane. Zhang Heibin became more domineering after giving birth to a son. She often spoke ill of Queen Inhyun in front of Suzong, saying that she wanted to poison the prince, which made Suzong even more alienated from Queen Inhyun.

In the first month of the fifteenth year of Emperor Suzong's reign (1689), Zhang Yuzhen was named the first-class "Jubilee Concubine". In April of the same year, Suzong deposed Queen Inhyun and Jin Guiren (Ningbi Jin family) for the crime of "jealousy", drove them out of the palace and demoted them back to their private homes. In May, Jang Ok-jung was promoted to the title of Princess of Joseon, and Southerners were appointed. Westerners who supported Queen Inhyun were expelled from the court, and important Western ministers such as Kim Soo-hyang and Song Si-yeol were killed (historically known as "Ji has changed the situation"). Since it was the period of mourning for Queen Zhuanglie at that time, the formal concubine ceremony was not held until the end of the mourning period in October of the following year (1690). Jang Yuzhen's parents were named Fuyuan Lord and Fuyuan respectively, and her brother Jang Xizai also became a robber general. Jang Yuzhen became the first and only princess in the Joseon Dynasty who was born as a middle-aged man and ascended to the position of mother of the country.

After Zhang Xibin was promoted to princess, she had to go through the canonization process of the Qing Dynasty, the suzerain country.

Shortly after Zhang Xi's concubine was promoted to the imperial concubine, Beibiansi requested to follow the example of North Korea's Chengzong who abolished the Yin family and established Queen Zhenxian and sent someone to He went to the Qing Dynasty, the suzerain country, to request for canonization, and Suzong agreed. Later, Zhang Xibin's close confidant Li Hang, Lord Dongping, was sent as an envoy to Beijing to ask for the title. Although it was agreed, the Qing court demanded a fine on the grounds that "the word "harem" in the memorial was inappropriate for the princes, and the word "Xuan" was included, which violated their taboo (the name of Emperor Kangxi of the Qing Dynasty was Xuan Ye)." In the first month of the sixteenth year of Suzong's reign (1690), envoys from the Qing Dynasty officially canonized Zhang Yuzhen as the royal concubine of Joseon. Suzong also sent envoys to Beijing to apologize for the inappropriate wording in the memorial. Emperor Kangxi ordered "Li Yin's writing to be pardoned." . After Zhang Yuzhen took charge of the central palace, she used her status as a princess to recruit party members in the court. She successfully gained the support of Min An and other southern factions, and her son Li Yun was established as the heir apparent. It can be said that he had overwhelming power for a while. Zhang Yuzhen gradually became old and beautiful. In order to protect Su Zong's favor, she rejected dissenters and beat the palace maids who were favored by Su Zong many times. Her arrogance and arrogance made Su Zong gradually hate her. At that time, the Westerners, who were opposed to the current situation due to losing power, took the opportunity to launch the "Min Fei Redefinition Movement" under the leadership of Jin Chunze and others. In order to balance the forces of all parties and restrain each other and suppress Zhang Yuzhen and the Southerners, Suzong secretly supported this, and the party struggle became more intense.

In the 20th year of Suzong's reign (1694), Zhang Yuzhen felt threatened, so she attempted to murder the deposed Min family through her brother Zhang Xizai. Unexpectedly, Suzong found out, and used this to eliminate all his party members, and Zhang Xizai was also exiled. Jeju Island. Soon, Suzong decided to welcome Queen Inxian back to the palace and re-establish her as a concubine, returning Zhang Yuzhen to her original status as a "jubilee concubine". At the same time, Xiren was re-employed (known as the "Jiaxu Change" in history). Zhang Xibi was deeply dissatisfied with this and appealed many times to no avail. Seven years later, in the 27th year of King Sukjong (1701), Queen Inhyun was critically ill. It is said that Zhang Heibin set up a shrine in the west hall of Jiushantang in Changgyeonggung Palace and asked wizards to do it, intending to harm Queen Inhyun. The palace maids were instructed to bury the ashes of dolls, sparrows, and mice in the front courtyards of Daejokjeon of Changdeokgung Palace and Tongmyeongjeon of Changgyeonggung Palace. After the death of Queen Inhyun, the matter was reported by Choi, the concubine of the palace. On September 28, Sukjong personally interrogated the maid involved in the incident at Injeongmun Gate of Changdeokgung Palace. Then they were all executed. The mastermind of the curse incident, Zhang Xibin, was the biological mother of the crown prince. Suzong hesitated for a while, and the ministers repeatedly advised him, but finally issued an edict on October 8, ordering Zhang Xibin to commit suicide. On October 10, the twenty-seventh year of Emperor Suzong's reign (1701), Zhang Xibi committed suicide by taking poison. "The Biography of Queen Inhyun" describes her death as follows: "The superior (referring to Suzong) had no compassion and poured three bowls of poisonous wine into Zhang's mouth. She only heard Zhang scream loudly and rolled down the stone steps. The blood surged like a spring. A little medicine was enough to make all the internal organs burst, not to mention three bowls of poisonous wine. In an instant, black blood spurted out from all Zhang's orifices and flowed to the ground. As a humble palace servant, he murdered the mother of the country and framed Zhongliang, and ended up like this. , is this not a disaster from heaven?" At the same time, Zhang Xizai, Zhang Xizai's brother, who had been exiled to Jeju Island, was also escorted back to Seoul and executed in front of the Military Temple on the charge of "murdering the mother of the country." His family members were also massacred, and all males over the age of sixteen were hanged. Zhang Xibin's relatives, the Yin family, the An family, and the southern minister Min An were also implicated and executed. However, Suzong did not demote Zhang Aibin to a commoner, nor did he depose the prince born to Zhang Aibin.

In view of Zhang Aibin's disaster, Emperor Suzong of Joseon issued an official decree the day before he ordered Zhang Aibin's death: "From now on, it will be the official code of the state, and no concubine can be used to ascend to the concubine." In the Joseon Dynasty, no harem concubines were promoted to princesses again. Ningbin Kim was recommended as the new princess by the dying Queen Inhyun, but Sukjong did not agree; and 200 years later during the Korean Empire, Emperor Junxian's concubine Uhm also launched the "Shangshu Movement", and Emperor Gaozong also No consent. It can be seen that Zhang Xibin’s lessons had a great influence on later generations.

Twenty years later, the crown prince Li Yun succeeded to the throne as Jingzong of Joseon. Jingzong has always enshrined his mother's spirit in the other hall in Houyuan. In the second year of King Jingzong's reign (1722), King Jingzong, based on the request of his ministers, posthumously named his mother Zhang Yuzhen the "eldest concubine of Yushan Prefecture" based on the story of King Seonjo of Joseon's honoring his biological father, Lord Dexing of Dexing, as the "Jun of Dexing Dawon". It is one of the "Seven Palaces" for the purpose of offering sacrifices to concubines.
