In Liaoning province, Chinese is the national unified edition, mathematics is the Beijing Normal University edition, and English is the Shanghai Education Edition. In recent years, with the requirements and changes of the Ministry of Education and the requirements of the Provincial Department of Education, we have been using the People's Education Edition before the change, and finally the Beijing Normal University Edition. However, whether it is the Ministry version, the Beijing Normal University version or the People's Education version, they all have different advantages.

Mathematics textbooks for primary schools in Heilongjiang Province should be PEP version, which is not uniform in the whole country. People's Education Edition, Soviet Education Edition, Beijing Normal University Edition.
