What do China and North Korea the two communist countries have in common as for their top leaders?

The answers are somewhat intriguing: the leaders of both China and North Korea are marked as the unprecedented revolutionary leaders in the world, while their most close relatives are all counter-revolutionists.

China:

Mao Zedong, the husband and revolutionist

versus

Jiang Qing, the wife and counter-revolutionist.

North Korea:

Kim Jong-un, the nephew and revolutionist

versus

Chang Song-thaek, the uncle and counter-revolutionist

Is it weird? NO. This is the very portrays of totalitarian regimes.
