The hand is the main organ for human touch;

The more complex, exquisite and skillful hand movements, especially finger movements, the more neural connections can be established in the cerebral cortex, thus making the brain smarter. Since ancient times, there have been common sayings and idioms such as "the heart governs the gods", "the fingers are connected to the heart" and "the ingenuity", which more vividly illustrate the close relationship between the hand and the brain.

Therefore, children who often do finger movements will have smarter brains and stronger concentration.
