Grasping the essence of things is called "truth". It is to seek truth in educational content and not to teach false knowledge.

Only "good" can play a good educational role.

It is called "goodness" according to its purpose. Education should be targeted, not whining about everything, that's really doing good.

Only by embodying beauty can the quality and efficiency of education be improved.

It is "beauty" that things complement each other. Educators should pay attention to adopting appropriate educational methods so that the content and form of education can resonate with the educated. Strive to let the educated experience the wonderful and wonderful "spring breeze melts rain, moistens things silently", which will be unforgettable for a long time.
