two things to get you started:
1. Find a good book with short stories (Chinese and English) and learn them by heart. This could be the most efficient way of improving your reading, writing and increasing your English words.
2. Watch English movies with Chinese subtitles. This is a good way to train your ear.
The most important thing is to make a lot of mistakes with thick skin, the more mistakes you make, the quicker you learn.
Hope this helps. Good Luck!
