Where can I buy Chinese textbooks and Chinese test papers for senior high schools and junior high schools in Beijing?

There are a series of papers called Tian Li ... which is better and more comprehensive. Generally speaking, textbooks can be ordered at school, you can try them, if not, you can borrow them from senior students! Or you can try to contact the manufacturer. If all the above methods fail, you can print the teaching materials on People's Education Network. But some schools, such as Tsinghua High School (or Haidian), are not easy to get, because they may have revised it themselves. However, in addition to the above-mentioned papers, you can also find the papers attached to the middle school of Beijing Normal University, which are relatively basic; Haidian's papers have strong comprehensive ability; In fact, I still recommend the thesis of Changchun International Studies University, but after using it, I feel that the basic emphasis seems to be different from most of Beijing. Well, good luck (reading and writing are the most important things in Chinese! )
