Hi, guys, long time to not update my blog in 博客园,Now, I'm studying in Denmark, and worked part-time in a start-up. Everything is fine now. For everyday I touch new things in my work and study, I want record them in my blogs, because they are so easy to be forgotten. Meanwhile, I think it is very hard to insist if I cost several hours to do this thing, I don't want to give up after several days:) So, I decide just to take about half a hour a day to do this meaningful thing. It's cooool.Hi, guys, long time to not update my blog in 博客园
