North Korean leader Kim Jong-un's younger sister Yo-jong is believed to have married a son of the country's second most powerful man Choe Ryong-hae, a secretary of the North's Worker's Party.
 
Reliable sources in China said Kim's 28-year old sister, a deputy director of the Workers' Party herself, married one of Choe's sons last year.
 
Choe is known to have two sons, including the eldest son,"Jun" in his late 30s, and the second son, "Song" in his early 30s, and a daughter. Sources suggested the North Korean leader's sister married the second son whose job title has not been confirmed.
 
In line with the intelligence, Kim Yo-jong was seen wearing a ring on the ring finger of her left hand in a photo released on the Friday edition of the North's state-run Rodong Sinmun. The daily said she accompanied her brother to a Pyongyang orphanage.
