According to the regulations of Zhejiang Education Department and Linping Education Bureau, the current science textbooks for primary schools are the new version of PEP. The textbooks of primary schools in Zhejiang Province are all quoted from People's Education Publishing House, because the textbooks of People's Education Edition are relatively standardized, easy to learn and understand, and students can learn well.

"People's Education Edition" refers to the "People's Education Edition", and the so-called "Edition" refers to the textbook edition, not the "Edition" of the publishing house. So "People's Education Edition" refers to the textbook version published by People's Education Publishing House. This set of textbooks is compiled by the Institute of Curriculum Textbooks and xx (Discipline) Curriculum Textbook R&D Center, and distributed by Xinhua Bookstore Group.
