How do you deal with people who like to complain?

I think those who love to complain are using it to vent their emotions. Complaint, as understood by the public, is probably close to complaining or venting. From a psychological point of view, it should be a kind of excretion. When people in society absorb enough negative energy brought by external information, they will reach a breaking point. This breaking point will all be "excreted" at a certain moment, and the best way to "excret" is to complain as much as possible, " The state of "vomiting" is particularly hearty and hearty, and is an expression of negative emotions. People with weak thinking ability have strong brain inertia and complain more frequently.
