It is not easy to run a good primary school trusteeship class. Although the sparrow is small, it has all aspects. On the premise of safety first, enrollment, logistics, teaching, communication between teachers and parents are all-round. Teacher Dou Kun, the founder of extension education, once said that student trusteeship is a sunrise industry. Under the impact of e-commerce, many physical stores closed down, but the number of custody classes and custody institutions increased. Home care classes have low operating costs and stable personnel. As long as the reputation is good, it is no problem to support the family. Large institutions have scale and processes, and it is easy to establish a good teaching team and form a brand. On the contrary, the trusteeship class caught in the middle is even more uncomfortable. The competition for custody of primary school students can be said to be quite cruel. If the market is not well divided and does not have its own characteristics, it will fall into a price war with the surrounding custody. The result of single-handedly fighting for low prices is bound to be a decline in service quality, and it will be difficult to operate in the end. Therefore, we should establish our own brand, form our own reputation and characteristics, and be in an invincible position.
