Hello Ajay,
Here are some tips to improve your writting skills in particular and your English in general:
- Write a film , music or a book review.
- Read books with lots of dialogues to improve the ability to speak and converse using various
expressions and idioms.
- Take a short intensive course to strengthen your week points whether grammar,pronunciation or
others.
- Watch English language movies with English subtitles or Chinese movies with English subtitles
as well.
- Look up new words and create vocabulary lists and go through them several times every day or
week.
- Keep a diary in English.
-Use online chats to converse with native English speakers and ask them possibly to correct your mistakes.
- Learn as many words as you can of one category e.g animal words , office words etc. list them
and revise them every now and then . Find comprehension texts of relevant subjects that might help
you revise those words in particular as e.g an article about wild life or distinct animals when revising the animal word list .
Good luck:)
