Exactly. They were heavily criticized by Chinese fans for saying "Lunar New Year" in English on Bubble instead of calling it Chinese New Year and doing the greeting in Chinese. They are literally damned if they do, damned if they don't.
Honestly from what I've seen they are handling the comeback well. They seem to do be doing the Chinese version on two/three music shows and the Korean version on two/three music shows. If they don't want to hear the Chinese version on Music Bank then just wait for the Korean version on Inkigayo.
