When I was young, I read Zhao Xinshan's Philosophy and the Contemporary World, which had a long-term impact on me. There is a passage in the book: an outstanding scientist must be a philosopher who shines at the same time and thinks independently. I comment on this page: Isn't education the same? Since then, I have a great ambition: to be a teacher, I must be an independent thinker and philosopher and become what Zhao Xinshan called a "three-dimensional" teacher. This ambition has changed my perspective of observing education and made clear the direction of my future efforts.
