I haven't been here for a long time, so I'm surprised  when i just opened this web page and found the comments, It never occurred to me that someboby would reply, thank you for all your encouragement.

      I think this is a good place to improve English skills, it gives us a platform to express ourself in English, and the most important is there are a lot of english lovers, as a result, we can communicate and learn form each other, come on!
