Chinese English

I've always believed that" Chinese English" is an irony joke for English learners who speak without any English basic concept since I learned English. I went to library today and the book named " Chinese Englishes" caught my eye. Originally, I thought it was a grammatical book. However, it certainly is not. The book, Chinese Englishes, explores the history of the English language in China from the arrival of the first English-speaking traders in the early 17 century to the present.
Englisg is no longer the possession of the British, or even the British and the Americans, but an international language which increasing people adopt for at least some of their purpose. All the teachers, except foreign teachers, who have taught me English always told me "English is a tool". I insist on my belief that "English is not a tool". I learn English for the purpose of interests. Well, can't interests be the purpose of learning English? I don't think so.
The hybridisation between European and Asian languages have a relatively lengthy history, as long as the movements of European trade and colonialism in Asia themselves. "New English" in Asia was predated by "new Portuguese" for at least a hundred years, and there is clear textual evidence to suggest that we can speak meaningfully about the origins of "Asian English"
Three weeks from now, the final exam is almost around the corner. I'd better to be prepared and it forces me to put this book away. Anyway, I will read it during winter vacation.
By the way, may I have someone to tell me what "Englishes" means? I can't look up it in the dictionary.
