昨天，我的信息老师说：“洛谷是什么垃圾玩意，大家要打CF！”于是我开始使用一年前注册的账户。今天，我看见一个人品很差的一个同学在洛谷上骗分，我觉得他污染了信息学。现在，我发现信息老师是对的，洛谷只是山丘，CF是珠穆朗玛峰——“不畏浮云遮望眼，自缘身在最高层。”

**Codeforces我来了！！！**

————————————————————————————————————————————————————————— Yesterday, my computer teacher said, "what kind of rubbish is luogu? We should go to CF!" So I started using the account I signed up for a year ago. Today, I saw a very bad character of a classmate on the luogu cheat points, I think he polluted the computer. Now, I found that the computer teacher was right, the luogu is just a hill, CF is mount Everest -- "do not fear clouds cover the eyes, self-premised body at the top."

**Codeforces here I come!!!**
