金與正
Kim is sometimes accompanied by his younger sister Kim Yo-jong, who is said to be instrumental in creating his public image and organising public events for him. According to Kim Yong-hyun, a professor of North Korean studies at Dongguk University in Seoul, and others, the promotion of Yo-jong and others is a sign that "the Kim Jong-un regime has ended its co-existence with the remnants of the previous Kim Jong-il regime by carrying out a generational replacement in the party's key elite posts".
