Hello, I'm from Xingyi, Southwest Guizhou. The textbooks used in Guizhou are not the same in all regions. I went to Xinhua Bookstore in Kunming this winter vacation. I am also a junior high school student. It is difficult for me to buy materials from you because the version is different. I am here: Chinese: People's Education Edition, Mathematics: People's Education Edition, English: Kindness Edition, Physics: People's Education Edition, Biology: People's Education Edition, Politics:. I only know your Chinese: Jiangsu Education Edition, Mathematics: People Education Edition, English: People Education New Goal, Physics: Shanghai Science Edition.
