Which series of textbooks is better for teachers' open recruitment examination? Tu Hua, Zhong Gong or Shan Xiang? I come from Hunan.

Every version is basically the same. Most of our classes are taught in rural areas. The content is relatively systematic and complete. There is also a way to list some knowledge points in Shanxiang Edition, which is also instructive for our review. After all, there are many things to recite, so it is good to be familiar with some of them, not all of them.
