Many parents will educate their children in kindergarten in advance because they are worried that their children can't keep up with primary school. However, this mechanical accumulation of knowledge may gain a temporary advantage, but at the expense of their long-term interest in learning.

1. Sacrifice children's opportunities for all-round development. It is easy for children to learn a lot of knowledge and skills when they mature to a certain extent, but deliberately advancing and accelerating their development will make children waste precious time on unsustainable mechanical memory, thus sacrificing opportunities for personality development and quality training.

2. Kill children's interest in learning. Before the age of 6, children do not have the ability of logical thinking. If they are forced to learn pinyin, literacy and arithmetic too early, children will only deliberately remember these shapes and symbols because they can't understand the meaning of words and arithmetic. Long-term passive absorption will make them lose the motivation to learn, and even have a feeling of weariness.

3. The immediate effect of "ahead" is difficult to maintain for a long time. There is a saying in the education circle called "the third grade effect", which means that many advanced children will easily get full marks because they have finished learning the content after entering the first grade, thus forming a bad habit of not listening carefully. When learning new knowledge in grade three, due to the lack of good learning attitude and habits as a support, the grades will drop sharply, and the development stamina will be insufficient, resulting in a sense of learning incompetence.
