Prince Gyeongnyeong

Biography
Yi Bi was born on 6 January 1403 (In the lunar calendar: 13 December 1402) to King Taejong and Royal Noble Consort Hyo of the Cheongpung Kim clan. Prior to becoming the king's concubine, Lady Kim was originally a maid at Min household who had been with Queen Wongyeong before she became queen. The prince was born after his mother entered the palace and King Taejong ascended the throne.

It said that he was kind-hearted and had strong filial piety. Yi was excellent at academics and taught his little brothers how to write.

It is said that his legal mother, Queen Wongyeong, and his biological mother did get along after his birth. But despite this, Yi Bi had a good relationship with his older brother, Yi Do (the future King Sejong) as well as his legal mother, and also helped the young prince with his education.

In governmental affairs, when there were difficulties in the royal family and in state affairs, the Prince tried to solve them with allegiance. For five generations, including Taejong, Sejong, Munjong, Danjong, and Sejo, he was loyal to and cooperated with the government.

In February 1416 (the 16th year of King Taejong), the 13-year-old prince and his younger half-sister, the 12-year-old Princess Jeongseon, married. The prince married the daughter of Kim Gwan while the princess married Nam Hui.

In 1419 (the 1st year of King Sejong), he became a teacher at the order of King Taejong, and went to Beijing in the Ming dynasty. He came back with gifts.

During the mourning period after Queen Wongyeong died in 1420, it is said that the prince scolded and argued with his father for having an affair with a Kisaeng named Im Jeom-hong. Rather than punishing the prince, King Sejong felt touched that his older brother reprimanded their father during a time of grief.

After King Sejo ascended to the throne, he moved to Chungju to spend the rest of his life there.

His tomb is situated on Geumsan Mountain, Chungju, Chungcheong Province, South Korea.
