Dear readers

I'd like to apologize to you first. This month, the books are rarely updated, and there is a break. I'm very sorry. It's not that I don't try to update, but that I'm really delayed because of a lot of things.

At work, new project R & D, every day to work more than ten hours, no time to update.

The child is hospitalized with high fever and pneumonia. Every day he is very busy until late. Sometimes he wants to update the code, and his brain is in a mess. He doesn't know how to write. Sometimes he falls asleep sitting next to the computer.

It's also very helpless to break the watch. Please forgive me and thank you for your support. I will continue to work hard. Thank you!!!
