Anyone can teach.
Teaching culture classes does not require a professional background in preschool education, and anyone can teach them. Moreover, it is relatively easy and cheap to hire such a "teacher". In contrast, professional preschool teachers are often difficult to hire.
Easy to manage
It's easy to manage only the culture class. Some private kindergartens have limited space and do not have enough outdoor activities, while the indoor environment is relatively easier to control and manage to ensure the safety of children. But it also means that children have lost the opportunity to learn in games and activities and can't experience the diversity and fun of kindergarten education.
Parents' expectations are too high.
Some parents expect too much from their children's educational achievements. They value how much cultural knowledge children can learn more than their all-round development. Therefore, teaching culture classes has become a way for some kindergartens to meet the needs of parents.
Overemphasis on cultural studies.
Too much emphasis on cultural learning is harmful to children's growth. Premature instilling knowledge into children may deprive them of the fun of childhood and the desire to explore. Real education should be to cultivate children's curiosity, creativity and autonomous learning ability.
