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.

生活本身就是一种冒险，充满了未知和挑战。

The more you know, the more you realize how little you know.

诗人是一个能在最丑陋的事物中找到美的人。

The energy transition is an opportunity, not a threat, for those willing to embrace change.
