Participating in various competitions in interest classes is not an IQ tax, because competitions can broaden people's horizons, provide direction for future study and increase performance experience.
Interest classes are also called super-long classes. There are many items to choose from, such as piano, violin, guitar and Orff music. Art classes include Chinese painting, ink painting, oil painting and sketch. Calligraphy classes include soft pen calligraphy and hard pen calligraphy. Physical education class includes swimming, roller skating and fencing. Parents should choose appropriate interest classes according to their children's interest points and age groups.
