1. Be a teacher all your life and learn to be a teacher all your life.

2. I have two "rulers", one is to measure the strengths of others, and the other is to measure my own shortcomings. Only when I see my own shortcomings or shortcomings can I have the driving force. Because, "A lot of trauma is the best thing that life can give you."

3. Once a person chooses the profession of teacher, he also chooses nobility. First of all, you must have "knowledge like a spring" and have great personality strength.
