The English language of People's Education Press is People's Education Press. The initials of the three words are "P, E, P", so the abbreviation PEP stands for "People's Education Publishing House". It happens that pep has "vitality" in English; Make it lively ",so here, it is extended to" happy, happy ". The coincidence of the two aspects reflects an important educational concept today, that is, I hope that primary school teachers can create a pleasant learning atmosphere for primary school students in class, so that students can learn in happiness and feel happy in learning, which can greatly improve teaching efficiency.
