分子的美在于它的结构和它的故事。
The beauty of a molecule is in its structure and its story.
The coal industry has a critical role to play in providing affordable and reliable energy while we transition to a lower-carbon future.
礼义廉耻,可以用来要求自己,不可用来要求别人。要求自己则能少犯过失,要求别人则难以与人和睦相处,难以与他人相处就不合乎处世之道。所以君子只严格要求自己,小人则对别人求全责备。
想要获得快乐就必须分享它,幸福天生就是双胞胎
