永远不要停止学习；世界总是在变化。
Never stop learning; the world is always changing.
煤炭的未来取决于我们能否使其更清洁、更高效。
Innovation is not just about technology; it's about changing the way we think and act to create a better future for all.
Oh,to struggle against great odds,to meet enemies undaunted.
If you get up in the morning and think the future is going to be better, it is a bright day. Otherwise, it's not.
