How to treat the phenomenon of parents hoarding teaching AIDS?

The phenomenon that parents hoard teaching materials is relatively small, which is also the practice of individual phenomena. It shows that everyone attaches great importance to children's learning and education, and the living standards at home are getting higher and higher. They are afraid that their children can't keep up with their studies and have more money in their pockets. It is understandable to buy more study materials, but there are not so many study materials for children to digest and absorb. On the other hand, it also reflects that parents pay more and more attention to social competition, fearing that teaching AIDS will be bought by others and children will lose at the starting line. So it's really hoarding. The printing house was overjoyed. Is this machine printing fast or did you buy it fast? !
