Mathematics textbooks generally use Beijing Normal University Edition, and only some schools use People's Education Edition, with a small number.
English subjects are very different. For example, in many public schools such as Jinjiang District, chenghua district and Pujiang County, English textbooks are published by People's Education Press, and some districts and counties use FLTRP.
English textbooks used in private schools are even different.
For example, the PEP English textbook used by Chengdu Jiaxiang Foreign Language School (primary school), the FLTRP textbook used by Ai Hua School in Pidu District of Chengdu, the Longman and FLTRP English versions used by Langang Foreign Language School in Shuangliu District of Chengdu, and even some foreign language schools involve supplementary teaching materials.
So, be sure to ask the teacher. For disciplines other than linguistics, Sichuan Beauty Edition is used for fine arts, Sichuan Education Edition is used for music and information technology.
