Describe a cheerful activity scene. (No more than 100 words.

Tonight, my mother and I went downstairs for a walk when we suddenly heard cheerful music. Walking in, it turned out that grandparents and aunts were dancing. Grandpa, grandma and aunts danced happily together listening to cheerful music, attracting many people around them. These dancing grandparents look younger. I think, while exercising, they are also adding luster to the creation of a national civilized city in our city.
