What are the advantages of collective piano lessons?

In the past, piano lessons were all one-on-one, but now it is the Internet age, keeping pace with the times, and no one goes to the boring piano one-on-one. Nowadays, piano group classes and piano music classrooms are popular, and the teaching mode integrating education, media, entertainment and games has increased children's interest in learning piano. Playing games while attending classes is entertaining, and the pleasant atmosphere of group classes is not available. Usually after a group class, children don't want to finish class, but want to continue.
