Why are the rumbled boys called Zhang Xueliang rumbled?

Why do people call Zhang Xueliang a rumble?

Because his father is the king of the Northeast, and his name is Zhang Dashuai, of course, he is called Jong after inheritance. There is a feeling of being a young master in it.

The eldest son of Zhang, the leader of the warlord in the northeast, was born in the era of warlord melee, and his mother died in his early years. Cleverness is Zhang's key training object. When I was young, I lived with my father's aura and was romantic and idle. Later, I was sent to the Army Military Academy by Zhang to exercise and study. Accompanied by thorns and obstacles on the road of growth, he turned the tide in the face of national justice and later became the leader of the Northeast Anti-Japanese War.
