过去是一个跟随我们的影子，无论我们跑得多快。
"The past is a shadow that follows us, no matter how fast we run."
引用俗语说明运势变化的无常性。
The truth is not always the easiest thing to believe.
——赠宋庆龄题词，1922年
If you love your work, you'll be out there every day trying to do it the best you possibly can, and pretty soon everybody around will catch the passion from you — like a fever.
I believe in the power of dreams and hard work.
发现的兴奋感永远不会消退。
