The first generation: the women's groups such as S.E.S were dissolved long ago, and all the members got married and had children. The second generation: 2ne 1, wondergirls, tara, f(x) and other girl groups were once brilliant, but almost all of them were dissolved. Three generations: girls' day, AOA, apink, exid, sistar, etc. , basically once a year. When they debuted, they were catching up with the glory of the second generation of women's groups, and now they are caught up by the fourth generation of women's groups. Overall, it's embarrassing. Four generations (key points): according to fire and paste, it is divided into five heavenly kings and seven fairies. The five heavenly kings include: twice, basically the first women's group, blackpink, SM's red hair, mamamoo, strong sound source, GFRIEND, and the representative of knife group dance. The seven fairies are too disgusting, among which lovelyz and the unspeakable group are slightly splashed, and there is also a momoland lit by the disco music. Five generations: the latest generation, representing the new Rubik's cube combination G-idle (probably spelled like this? ) and pd48 are also five generations.
