可持续性不是一种选择；而是我们对后代的责任。

Civilization is a stream with banks. The stream is sometimes filled with blood from people killing, stealing, shouting and doing the things historians usually record, while on the banks, unnoticed, people build homes, make love, raise children, sing songs, write poetry and even whittle statues. The story of civilization is the story of what happened on the banks.

跨越万里山川，拨开云雾前进；经历百次寒暑，踏着霜雨前行。

"The human heart is a mystery, even to itself."
