There’s the one in Shang Chi where his dad says something like “Be careful how you speak to me. I’ve lived ten of your lifetimes.” in Chinese to another high ranking person, but what he really said was, “I’ve eaten more salt than you have eaten rice.” which sounds much cooler IMO.
I’m sure if you’re super into the lore then this will be a great movie for you but man, it was so boring for me. The exposition ratio is way too high, it really could have used more animatronic screen time and action instead of the frequent dream sequences.
