照片实际上是所指物的散发。从一个曾经在那里的真实身体，发出的辐射最终触及到我，我在这里。

The study of mathematics is a journey without an end.
用谦虚培养自己的品质，用修德提高自己的思想，用仁爱对待天下万物，用道德教诲子孙后代。
The essence of a good life is to live without any sense of hurry.
"Happiness is not something ready-made. It comes from your own actions."
The only way to learn mathematics is to do mathematics.
