So we all know there's different types of chinese, most popular being mandarin and cantonese. Some members can sing mandarin but not cantonese or vice versa and since the characters are generally written the same it's hard to tell which the song itself is so this is my solution:
Instead of writing [CHINESE] in front of your collabs, please put
[MANDO] [MANDARIN] for mandarin
or
[CANTO] [CANTONESE] for cantonese
^_^ Hope this lessens confusion.
