To look at a thing is very different from seeing a thing. One does not see anything until one sees its beauty. Then and then only, does it come into existence.

不忘初心，方得始终，我们要始终牢记"我为祖国献石油"的使命。

The best way to appreciate your job is to imagine yourself without one.

即使面对挑战，质量也绝不能妥协。

"We are all completely different people at different points in our lives."

"The essence of mathematics lies in its freedom."
