Why doesn't Zhang Xueliang like to call him Jong?

Because Zhang Xueliang has a strong nature, although he is the son of Zhang Zuo Lin, the king of Northeast China, Zhang Xueliang doesn't want to get everything he wants by relying on his father's reputation. People call Zhang a "coach", so Zhang Xueliang is naturally a "young coach". A seemingly normal title means contempt for Zhang Xueliang.

Zhang Xueliang still works hard. He hopes to get everything by his own efforts, so he doesn't want others to know that he is a "rumble". Zhang Xueliang is a Christian. Like many religions, Christianity teaches us to get results through hard work.

However, the title of "Jong" is obviously related to Zhang's identity. It seems that everything about Zhang Xueliang was given by his father in a word, which made Zhang Xueliang feel uncomfortable and useless, so he didn't like being called "rumbled", so his subordinates usually called Zhang Xueliang by his position.
