Be low more and more

"Be low" is a necessary thing in China, just like the words in the above picture presents.
In recent days, I felt more and more harsh to be low.
One of heads of my department told the management class to give me a lesson for some reason.
May be when I leave present department, I can smile, of course no one knows why I can smile, and my smile is greatly different from that of Gaojianhua when leaving HP.
I smile because I have gotten the lesson which is very important for my future, so I thanked head of my department. Sometimes who can give you a lesson may be not a bad guy, he just want to implement his own purpose.
But I think that everyone should be responsible for what he does.
Now I can accept lessons people give me, because I know what I do, but I am sure everyone should be responsible for what he does!
