Query: Unbelievable for a Chinese reader

My first language is English but I am bilingual. The Chinese (phonetic approximation) used in these books is nonsensical. I found it virtually impossible to read. Perhaps readers who have zero knowledge of Chinese will find it plausible. To me, it is like reading a book that calls a laser rifle a "black knife". It's that bad. I had to mentally make up futuristic Chinese words myself just to wade through the prose. Hell, it would have been easier if it was GREEK! Good try, but sorry, the author should have become conversant with modern pinyin Mandarin before attempting this series.
