My purpose at the current stage is using the words I know. Chinese who is in the same age with me learned English from primary school,and is one of the three most important subjects at high school(the other two are Chinese and math ).But because there's not so much situation to speak English,I forgot most of English words when graduated from school. At least I can use the most simple words to explain what I'm thinking now.Maybe restart English learning is not so difficult as I think.
