First, exercise?
At the age of aunts, there are too few forms of exercise that can be carried out. Too intense exercise makes their bodies can't bear it anymore. The sudden emergence of square dance made the aunts shine and joined in. The intensity of square dance is not very strong, just suitable for their age. They can move all over without jumping very hard. It is a very happy thing to move with the music.
Not only that, some aunts who love beauty feel that they have realized their wishes, both fitness and dancing. Why not?
Second, eliminate your inner loneliness?
Now there are more and more survival rules in this society. There are only a few old people left in some rural areas, and most young people have gone to big cities to work hard. If you leave your hometown, you may never go back for a long time. The elders in the family don't see anyone every day. When they are old, they need the company of their families more. Family members are away for a long time, and it is inevitable to be lonely inside.
Only the rise of square dance has eliminated the loneliness of some aunts. It's much better to have a group of people with the same hobbies every day than to be alone. So this is also a big part of the reason for the sudden emergence of square dance. A group of aunts danced and twisted together, and the loneliness in their hearts was blocked by more than half, so young people also remembered to go home and spend more time with their elders and parents.
Third, products left over from the times.
Why do you say that? Since ancient times, women have been a group that loves beauty. They are all born with temperament in their bones. Most human beings live in groups and like lively atmosphere. The square dance reflects these.
Some aunts have never been exposed to these forms of entertainment when they were children, and those who like dancing have no financial ability to develop in this respect. They can't get what they like when they are young, but they certainly don't want to miss it in middle age. At least, they always do what they like.
