I asked other classes roughly, and some said they didn't charge the shift fee, some paid 200,300, and even heard that there was another 500. Our class spends money on extracurricular exercises, exercise books and books. And various class activities. If there are 40 people in a class, each person has 300 yuan, which is more than 10 thousand yuan. How to manage and operate the class fee is also a sensitive issue, after all, it is a small treasury.
