The waterfall sing, I find my song, when I find my freedom。
瀑布歌唱道:我得到自由时便有了歌声了。
Mathematics is not a careful march down a well-cleared highway, but a journey into a strange wilderness, where the explorers often get lost.
Don’t wait for the storm to pass; dance in the rain.
I must study politics and war, tapestry and porcelain.
