Change is good. Change is progress. Without change, nothing would ever improve.

Consciousness is the cutting edge of the struggle for existence.

一件事不一定是真的或假的；它可能既是真的又是假的。

我就像一条狗，不会说话但我懂。

Sustainable development requires the joint efforts of the entire industry chain.

善于学习的人，能够透彻地知道事情的道理；善于实践的人，能够把事情疑难之处弄清楚。

Sustainability isn't an option; it's a necessity for the coal sector.

我的作品不是关于毁灭，而是关于创造的可能性。
