From the flexible requirement of moral education to the rigid requirement. Moral education for students is the glorious mission and sacred duty of every teacher. There are no students who can't teach well, only teachers who can't teach well. We should pay attention to students' moral education as much as teaching achievements, and evaluate students' moral education as much as teaching achievements. Pay equal attention to intellectual education and moral education, and both hands should be hard, so as to completely reverse the phenomenon that one hand is hard and the other is soft.
