I'm running this one this week and while doing my prep I had a thought and figured I would throw it out to more experienced GMs than myself.
It says that Shang Xu can throw anything... Would that include a PC? If he is throwing rocks at the PCs and one comes right up into his grill, my thought would to grapple the PC and throw him at another PC. Maybe not the best action economy for the monster but I think it would be epic fun.
