The second volume of Guangdong's second grade mathematics is the People's Education Edition, but the textbooks are basically updated every year. In fact, many contents of Chinese and mathematics were not learned by us in the 1970s and 1980s. Especially in the Chinese class, except for a few big coffee articles such as Tang poetry and Lu Xun, the content of the text has basically been replaced. Of course, we must keep pace with the times. Old and dead things need to be updated.
