Don't draw a conclusion without seeing it with your own eyes. Even if you see it with your own eyes, you should listen to the employees' explanations, because some things can be known without looking at the surface, and your attitude towards employees must be good. However, when employees make mistakes, you must think about why such mistakes occur, and whether such mistakes are directly related to yourself or indirectly.
When it comes to the mistakes and gains of employees in dealing with problems, we should also think about how they would handle this problem if they were themselves. When you don't know anything, don't say it's to save face and don't want to ask others. In fact, there is nothing worth saying in this world to save face or something! The real face is that you have learned such things, knowing how to do these things is your real talent, and let others think that you are excellent. Worthy of respect!
