Hi Zhaoqiang, I'm Anh, a professional language trainer. Personally I see no inherent harm in translating from your first language (Chinese) to a second language (English). This process becomes counter-productive when you depend too much on translation and get stuck when not finding the right translation for your idea. Not living in an English-speaking environment is the main difficulty for most learners of English as a foreign language. But you can create that environment in a way - by watching videos, reading books or the news, listening to podcasts... Try to make English part of your everyday life. For example, when you look for information in Wikipedia, put it in English. There's no secret about thinking in a language. You just need to train your brain.
