ACV
Abbreviated Chinese Vernacular. An evolution of Chinglish; often resulting from having spent too much time studying Chinese in China. The acronym for Abbreviated Chinese Vernacular is ACV. ACV is actually a sub-lingual dialect of Chinese.
English: Hey friends, if you want to return to America because you don't like China, don't worry. You just need to tell me why you feel uncomfortable, and I will immediately understand.

Real Chinese: Nihao pengyou'men, ruguo ni xiang hui Meiguo yinwei ni buxihuan Zhongguo shenghuo, mei shi. Ni jiu neng gaosu wo weishenme ni juede bushufu, wo yixiazi mingbai.
