It is said that disaster comes from the mouth, but you should talk when communicating with others. Is it better to talk more or less?

Don't talk, and you can't say too much. Grasping this degree well reflects the art of speaking.

We should be able to distinguish between good people and bad people. Don't say what some people should and shouldn't say, while others can say it with confidence.

It is very important to grasp the timing of speaking. When to say what, when friends are in a good mood, you should talk about some light topics, and when they are in a bad mood, you should comfort them more.

I hope it helps you.
