How to understand the phrase "communication errors caused by China people" often used in management?

The word "speak Chinese" also has many meanings, just like the joke I said before. The general idea is that a China person asks a foreigner to go to the toilet, and then the foreigner understands that convenience is to solve personal physiological problems. Later, I met a China man and said that he wanted to talk to him about something at his convenience. Then the foreigner ignored him and thought about how to talk about things at his convenience. I thought the same thing.
