Weiqi is an advanced intellectual gymnastics, so it is better to learn it at a young age. Especially at the age of 2-3, it is not suitable for learning. Children who are too young have limited understanding and acceptance and weak self-control. In the usual observation, it is not difficult to find that some children aged 2-3 can't express themselves clearly, and children who are too young can't count. Even if they can count, there are few children who can count 100. Even if they can count, it is normal not to know the numbers. The learning process of Go involves numbers, numbers, spatial layout and many technical terms. The comprehension ability of these words greatly exceeds that of younger children. Once children form a bad idea about the toy "Go" in the process of contact, it is likely to dampen children's interest in exploring and learning new knowledge and their confidence in future study, which is counterproductive.
