The reason why everyone cares about wages and bonuses is because it is something that everyone will care about. It is not only closely related to your own life, but also closely related to whether your work ability is recognized by your superiors.
These two points are far more important than talking and laughing together. Ability determines wages, others can't get low wages, and you can't get high wages if you are strong, which is fair. However, if someone asks you in the future, you will joke that this is an industry secret. Normal people know you don't want to answer, so they don't ask questions.
Don't state your income in the future. Wages vary from person to person. Not everyone will get a high salary, because everyone does different jobs. If they want to get to the bottom of it, just pretend something is wrong and run out.
