Hi!
I love EXO too! They are a South Korean/Chinese group, that can be split into EXO-K, EXO-M, or can perform as EXO as a whole. When working separately EXO-K is generally in charge of songs and promotions in South Korea, whereas EXO-M is in charge of songs and promotions in China. The majority of the guys are Korean, with the exception of Lay (Zhang Yixing) who is the last Chinese member. There used to be twelve members, however, three of the Chinese members left, so now there are only nine. Not that we love them any less! That being said, although it is in China, there are Korean members in EXO-M; but nowadays things are mostly done as EXO (rather than in sub-groups).
Any other questions let me know :)
