材料有自己的智慧。

A sound mind in a sound body, is a short, but full description of a happy state in this World: he that has these two, has little more to wish for; and he that wants either of them, will be little the better for anything else. Men’s happiness or misery is most part of their own making. He, whose mind directs not wisely, will never take the right way; and he, whose body is crazy and feeble, will never be able to advance in it.

没有行动的理想只是梦想。

循环经济不仅仅是一个理想；它是我们行业的必需品。

运用神机的人，众人不知道他的功劳，在明处争斗不休的人，众人却都知道他。
