This sentence originated from Mr. Chen's famous saying that "there are no students who can't teach well, only teachers who can't teach well", and "there are no unqualified students, only unqualified teachers" is the most famous sentence among many famous sayings derived from this. I don't think that when Mr. Chen wrote this sentence, he wouldn't have thought that it would cause such a big discussion many years later.

This sentence is not absolute. There are many reasons for unqualified students. Each student's own conditions and living environment are completely different. It is impossible for teachers to take full responsibility for unqualified students.

However, teachers should never turn a blind eye to students with low academic qualifications and poor grades and let them die. Teachers should actively find ways to help students find the reasons for backwardness, pay more attention and guidance at ordinary times, and help them catch up with their grades as soon as possible.

In teaching, teachers who expand materials need to "taste pears with their own eyes and know the depth of the river with their own hands". Their courage to practice and face reality deserves admiration.

In fact, in most classes, some students don't paste mud on the wall, and dog meat can't sit on the main table. Confucius treats his helpless students, such as the student who doesn't go to class but sleeps at home. The evaluation given by this person is that "rotten wood cannot be carved."

Among the students taught by teachers, not all students are pillars of talent. Confucius, the originator of education, left the "most holy" students helpless.
