This is really useless...our class has tried it, and it was written jointly by three classes, and there was no reply. Later, we used Weibo to spread the word and even @ the principal. He forced the blogger to delete Weibo and used some official language to educate us. After all this trouble, we still haven't been given a new teacher. The teacher may know the students' behavior and find trouble in class to hurt us. Fortunately, we are in a liberal arts class and he is a chemistry teacher, so the impact will not be that big. You also think about it from another perspective. Fortunately, your teacher teaches Chinese. Self-study of Chinese is not a problem, but if she teaches mathematics or English, it will be a big problem. . Study hard, come on.
