What dances do children's dance, campus dance and middle-aged and elderly dance belong to?

There is no answer to your question. Dance regardless of age. Children dance includes modern dance, jazz dance, folk dance, Latin dance and so on. There are also campus dances and middle-aged and elderly dances, but they may often be campus group dances, sports dances (there are many kinds of sports dances), campus waltzes, and middle-aged and elderly dances are square dances, aerobics and ballroom dances. You must know the types of dance. Children's dance, campus dance and middle-aged and elderly dance only refer to the age of the dancers. You have never met such a question about the types of dance before. Children dance is not considered a dance. Just like asking what the pianos of teenagers and adults belong to, they both play Chopin and Liszt, and they are both classical and popular, but they will not be divided by which pianos belong to teenagers and which pianos belong to adults. The same reason
