Why is square dancing slowly becoming less popular?

According to me in Harbin and I stayed in the northeastern city to see, square dance did not become less, of course, not square dance just came out of the boom as, I think, the reason for this, there may be two reasons for it, the first is that when the old people are keen on the square dance has been old, is not suitable for the square dance, some of the younger older people are not too keen on the square dance, the second is that all people like the old and new, the square dance has existed for so many years, some of the square dance has been tired of it, so do not jump. After so many years, some of the square dance has been tired of, so do not jump it.
