The path of revolution is not a path of roses.

过去总是与我们同在，但它不必定义我们的未来。

The dialogue between light and shadow creates architecture.

任何实验的价值和效用都取决于材料是否适合其使用的目的。

Quality is never an accident; it's the result of intelligent effort and relentless focus.

Program testing can be used to show the presence of bugs, but never to show their absence!

因此圣人不期望因循古代，不效法常规。
