1. Environmental square dance is worth promoting! After all, noise pollution is too devastating! Sound is a mandatory media, for music, all you do not like is noise, not to mention the carrot and greens, that's why the public party is so obnoxious.
Square dance music is all brainwashing songs that some older people like, and some of the lyrics are so vile that many young people can't stand them. It would be nice if there was a way to keep this noise from always disturbing people!
2. If the so-called environmentally friendly square dancing means wearing headphones, that's not good. As we all know, wearing headphones for a long time or at too high a volume can damage your hearing, and this damage is irreversible.
Elderly people's hearing and eyesight are in decline, and they can't afford this! Still have to think of other ways to meet the needs of the elderly square dancing, but will not disturb the people causing noise pollution!
