What interest classes are there for four-year-old children?

Four-year-old children can apply for painting and dancing, and they should choose according to their own interests and characteristics. Abacus mental arithmetic is not suitable for four-year-olds because it requires strong self-control and attention, and it also needs to write numbers. Five-year-olds are usually recruited. However, it is recommended not to give abacus to children, because some children will affect the longitudinal study of mathematics in school in the future.
