I'm back

Hi Guys, Long time no see. I did not write blog has been more than a year before and less time for other reasons, microblogging stop updating. More recently, encouraged by a teacher, and we finally began to continue learning together. Haha, in fact, write blog is written for its own memory is not good, easy later retrieval. Of course, if able to help everyone, but also very happy. There is not the right place, I want to see the chiefs, to be corrected. Thanks very much.
