Sometimes school is under a tree, or in many cases, the teacher has only a fifth-grade education, so you need a collaborative model of learning, not just building more schools and training more teachers, which you have to do anyway.
有时学校就在一棵树底下， 并且很多老师都只有小学五年级的受教育水平， 因此你需要创建一个互相学习的合作模型， 而不仅仅是建立更多所学校以及培训更多的教师， 但这也是你无论如何都要做的。
