    Square dancing bus been more and more popular with the elderly as their living conditions improve, Most people thought it can help people take regularly exercise and strengthen their fitness. Besides, it provides people more chances to take activity outdoors. However, some people argue that the music is very noisy, that disturbs the surrounding citizens' normal life. Also, be exposed to such loud noise may do a harm to their health in the long run.

    In my opinion, square dancing is a good form of exercise, so dancers should take our neighbors' needs into consideration. If they choose a right time and turn down the music, it will cause fewer trouble for others.
