金與正
Kim Yo-jong is the youngest child of former North Korean leader Kim Jong-il and his consort, Ko Yong-hui. The U.S. Treasury lists her birthdate as 26 September 1989, while South Korean sources place her birth on 26 September 1987. Born in Pyongyang, she spent most of her early childhood at her mother's residence, growing up alongside her siblings. Between 1996 and December 2000, Kim studied with her elder brothers at the Liebefeld-Steinhölzli public school in Bern, Switzerland, under the assumed name "Pak Mi-hyang". During this time, she is believed to have developed a close relationship with her brother and future leader, Kim Jong-un. After returning to Pyongyang, she completed a degree in computer science at Kim Il-sung University.
