The word "tricky" is familiar to many people. I think it is beneficial for teachers to buy auxiliary teaching materials. If you answer that, it is no good getting up early. How can teachers be so keen on letting children buy teaching AIDS without benefits? Now people in society are blinded by interests, and some parents look at people with colored glasses. Teachers may be carried away by temporary interests, but they can't stand the temptation in the face of interests, so they pay attention to students, start earning money from them, and keep asking students to buy different materials, which not only increases the burden on students, but also increases the burden on parents.

The teaching and research groups of all subjects in the school will select one or several workbooks before the start of school, but the process of selecting workbooks is full of twists and turns. Teaching and research groups can't choose what they think is useful at will, because public schools need to choose according to the list of books given by suppliers, and often they don't necessarily have what they like. For example, in some places, there will be many booksellers, and the books represented by each bookseller are different, so this kind of books has a monopoly. Booksellers say that if there are no booksellers, there really are no local booksellers. Generally speaking, there will be a discount for school orders, such as 60% discount, but some booksellers will stock up and get a 20% discount. In addition, some booksellers and teachers have interests. Teachers ask students to buy materials and will take commission from them. In this way, the teacher will strongly recommend some materials, which may be useless and increase the burden on students.

Sometimes, the school will uniformly let students buy materials. Because the above booksellers, the price will not be much cheaper than the original price of the book, or even equivalent. Great, some self-righteous parents think: How can the school order in bulk without discount? The teacher must have pocketed his own money and made money in the name of ordering books, so he joined some parents to sue the school leaders, the district education bureau and even the municipal education bureau. So, in this era when doing nothing is good, who wants to be this good person?
