Grandma knows the periodic table by heart. Do you still remember the periodic table of elements recited in junior high school?

With the popularization of nine-year compulsory education, almost no one of us has never attended junior high school. Do you still remember the periodic table of elements that junior middle school chemistry must recite? At that time, when I heard the chemistry teacher say that we had to recite the periodic table of elements, we were almost devastated. Fortunately, we just need to recite the first twenty words, otherwise we would really cry at that time, and we haven't recited all the words in the periodic table, and there are still many unnecessary words. Not only are there no textbooks, but even exams are not given. But at that time, the teacher taught us with homophonic method, and soon we recited the first twenty elements. At that time, we were happy for a long time, because the teacher said that the periodic table of elements was really difficult, and later it was discovered that the teacher encouraged us.

Since we graduated from society, we have gradually forgotten a lot of knowledge we learned in school. Because we don't need it in our work, the knowledge we don't need will be slowly forgotten by our brains until it is completely forgotten. However, an 86-year-old grandmother in Zhoukou, Henan Province can recite the periodic table completely. It is understood that the old woman turned out to be a retired teacher and had taught chemistry before. After years of teaching, she has imprinted the periodic table on her mind, which is hard to forget. After netizens heard about this, they all felt that grandma was really dedicated. After so long, her memory can still be so deep. If she were herself, she would never recite it.

In fact, it can be seen from this incident that the old lady misses her teaching career very much and must be full of enthusiasm when teaching. So long after she retired, she still deeply remembered the knowledge in the textbook. I admire such a dedicated person, because such a person will integrate his work into his life and try his best to do it well. This kind of person is exactly what the country needs and what our people need very much.
