Revision: The publishing house didn't change the contents of the old edition of the textbook, but only did a little processing on the textbook, slightly adjusted the bibliography, abridged or added some contents.

New curriculum standard: refers to textbooks published in accordance with the requirements of the new curriculum standard of the national education syllabus.

Buy an atlas that is consistent with the version of the textbook you use. For example, if you use the revised textbook of PEP, then buy the revised atlas of PEP. If the textbook you use is the textbook of the new curriculum standard of Beijing Normal University, you should buy the supporting atlas of the new curriculum standard of Beijing Normal University. Both the revised edition and the new curriculum standards are indicated in the textbook.

You can also ask the geography teacher what version of the textbook you studied, and then buy a matching atlas.

Generally speaking, atlas and teaching materials are distributed to students together, and students do not need to buy them separately.
