Many painting courses actually don't teach basic painting skills, but focus on copying images or carrying out simple manual art projects, such as stickers or coloring. This type of painting instruction may not help to improve children's creativity and imagination, and may have a negative impact on the ability to convey truly original ideas.

In addition, some training institutions pursue efficiency and results too much, which will put too much pressure on children. If painting becomes a task, it will lose the sense of fun and freedom, thus weakening children's love for art.

Finally, it costs a lot of money to go to a training institution to learn painting, but in fact, most children can finish painting at home and get more freedom and fun in the process.
