Chu Shuzhi could easily take care of himself in that environment, but taking on bodyguard duties is a whole 'nother level of potential trouble.

That's such a good point! And despite that, Chu Shuzhi doesn't hesitate to extend his protection. (I wonder if having Guo Changcheng there makes him more careful and restrained, because he can't afford to lose control of the situation or Changcheng could get hurt? Like, if Changcheng hadn't been there, how much more confrontational would Chu Shuzhi have been??)
