The outside world is full of danger, but here is no challenge of life, is doomed to no applaus.My math has always been a broken leg .In many times mathematics can only bring me the endless boring. I don't like this kind of life. However, from this week onwards perhaps this is not the same. Cooperation is a great feeling, though I can't help what busy, but the feeling of trying my bestalways pleasant. Thanks to the campaign!外面的世界充满危险，但没有挑战的生活，注定无人喝彩。我的数学一直是个残腿。在很多时候数学能带给我的只是无尽的枯燥乏味。我不喜爱这样的生活。然而，从这周起我的想法或许就此不一样了。合作的感觉很棒，尽管我帮不上什么忙，但是做到了力所能及的事情总是令人心情愉悦。感谢这次挑战！Crystal
