原创钻展算弄完了，Happy！~ 来掰一下表白老姚~~ 哈哈

Yao is a very nice teacher,  fancy, cute and owns much useful information.
It's highly appreciated for me to be one of his students.
He always keeps patient on our homeworks and on nearly everything.
Things turn out to be harmonious after his dealing.
He always has methods to make the work charming.
Thank you very much for all your helping,
Sincerely yours and Happy New Year,
Mary 小萍

以下为钻展各稿大致过程，虽然我很菜， 无论上面毛躁地总结，还是下面的过程稿件。

看着不好也不能丢砖头，老姚会生气的哦~
