In China, chopsticks are the best tool for us to eat. According to the laws of fine motor development, children should start practicing using chopsticks to eat from around three years old. Khomlinsky, a famous educator in the former Soviet Union, said: "Children's wisdom lies in their fingers." Some people also compare their hands to the "teachers" of the brain. As the saying goes, "Skillful hands promote the soul." Children should practice using chopsticks when they are about 3 years old. This stage is a critical period for children's intellectual development, and the seemingly simple use of chopsticks contains great connotations and potential. It not only requires a good sitting posture to maintain body stability, but also requires more than 30 upper limbs such as shoulders, elbows, wrists, and fingers. The coordinated movement of large and small joints and more than 50 muscles. These hand joints and muscles can only complete the action of picking up food under the instructions of the central nervous system of the brain. This action stimulates brain cells and promotes children's brain development. development; at the same time, when using chopsticks to pick up food, hand-eye coordination is also required, and the eyes are used to locate and form visual images. This process requires the balance and coordination of the extraocular muscles of the two eyes and the imaging of the fovea of ​​the retina, which is very important for children's visual development. It has a great promoting effect and can also prevent strabismus and amblyopia in babies. Therefore, using chopsticks not only exercises various finger movements and hand-eye coordination but also improves children's thinking ability, creative ability, and operating skills. It is one of the important means to practice the use of both hands and brain.
