i can kind of see what you mean but now that i think about it, most of chinaline can speak korean anyway and obviously would've been trainees = integrated into korean culture. in the end they are still a "hallyu" group that is based on korea unless sm decides to make groups that are exclusively for china; that said i do think that replacing xiumin/chen with two chinese trainees who went through the same process as the current chinaline wouldn't really change a thing
