Why need I post this blog in English?
It's not for "Zhuangbi", for I haven't installed Chinese input method on my laptop...
I haven't post a single blog for sometime, maybe I turned more lazy...
Selection of Team of Province is coming, so I took much of my time to do some practice.
In my opinion, maybe it's times to write down some solutions of problems deserving it.
It helped me to recall some important parts.
So, that's all, time to go back on business.
