It must be cultivated from early childhood. Whether it is to improve the quality of the population or to cultivate seedlings, a large number of studies at home and abroad show that eugenics is enough to cultivate a good child, and early education is the cradle of high-quality talents. Early education is the best period for the development of human intelligence. If the right to education is deprived in this best period, children's development will get twice the result with half the effort. If children are completely deprived of this right to early education, then their intelligence and human behavior will be completely buried. According to the theory of intelligence development put forward by a Japanese scholar, the development of intelligence is like an isosceles triangle, which develops fastest at the age of zero, that is, at the bottom of the triangle, it reaches the top of the triangle at the age of eight, and intelligence no longer develops. After that, people can only increase their knowledge and skills. The ancients said, "If the son doesn't teach, the father has made a mistake." . Today we should say, "If you don't teach early, your parents will." . Parents must start with their children as soon as possible, educate their children about their physical and mental development, and create conditions for their children to take the first step in their life journey.
