Children are interested in martial arts, want to learn martial arts, and don't want to delay cultural classes. What kind of school should they look for?

My opinion is the same as yours. You can't leave the culture class behind when practicing martial arts. I know that a city acrobatic art school not only teaches martial arts, but also takes into account cultural classes. My cousin's children studied martial arts there, and they didn't fall behind in their studies. The children came back and said that the school often took them out for social practice, and the children increased a lot of knowledge. My sister consulted them directly, official website. You can try.
