How do the three basketball referees in CBA cooperate?

This is not a place to talk about basketball, but a place to spit feces, but I still answer you. It used to be called referee or center line referee, and two of them were bottom line referees, but now they have changed their names. But the two baseline referees are not just half-court, only the referees run around the baseline of their respective half-court. If there are differences, they mainly listen to the referee. The bottom line referee and the referee are opposite, that is, the referee is on the left.
