Boss Xie, whose name was Xie Rongsheng, belonged to the Xie Family of Nandu.
By way of analogy, if this were in Zhonghai, then the Xie Family would be equivalent to the Song Family of Zhonghai, and Xie Rongsheng would be akin to a member of the Zhonghai Four Young Masters.
However, it's worth mentioning that Nandu had only one dominant Xie Family, unlike Zhonghai, where several forces maintained a balance of power.
That is to say, in Nandu, there was no such thing as the 'Nandu Four Young Masters'; the offspring of the Xie Family were the most formidable by far, and their peers paled in comparison!
When Xie Rongsheng asked how many people were involved, Brother Shan immediately stuttered, not knowing how to respond.
