Digression (can be skipped)

I believe this article has let everyone wait too long, not my mysterious, hanging everyone's appetite, but to write an article really need to spend too much time. Perhaps an article, you spend 3-5 minutes to read, school will master, and I have to spend 2-3 hours to complete, perhaps only the intention to write the article people can experience, I hope we can understand each other!
