Discrediting chinese album sales has always been a thing in kpop, like discrediting SEA fans support.
For Twice, kpop fans even came with the excuse years ago that they were lacking chinese sales but they had big sales just because of japanese fans.
Having chinese fans buying albums is always used as a drag like: "it's chinese bots" or "most of them are chinese bulk buying".
Do kpop fans think sales should only come from Korea?
