The Langlands program is a reflection of the beauty and depth of mathematical thought.
生活要么是一次大胆的冒险，要么什么都不是。
Courtesy costs nothing. Lower the toilet seat after use. Let the people in the elevator exit before you enter. Return shopping carts to their designated areas. When you borrow something， return it better shape (filled up， cleaned) than when you got it.
结交朋友应该找超过自己的人，和自己差不多或不如自己的人不如不交。
Customer needs are our pursuit. We must win customer trust and satisfaction with high-quality products and services.
