Chen Heqin, a famous educator, said: "There are no students who can't teach, only teachers who can't teach." As soon as this language came out, the audience applauded. This famous saying comes from Mr. Chen Heqin, a famous child education expert in modern times. At first, this sentence was just a word used by Mr. Chen Heqin to encourage himself. The original intention is that teachers should constantly improve their education level, cherish every student and teach students in accordance with their aptitude. Perhaps Mr. Chen Heqin himself didn't expect that this sentence was "taken out of context" by some education administrators and regarded as the golden rule of demanding teachers, knocking over a large number of front-line teachers with one pole.
