Never stop learning, because the world never stops changing.

廣東話諺語

I am a writer because I need to tell stories. It's a way of understanding life.

我相信堅持的力量。

And I hope you will come back here to Harvard 30 years from now and reflect on what you have done with your talent and your energy. I hope you will judge yourselves not on your professional accomplishments alone, but also on how well you have addressed the world's deepest inequities…on how well you treated people a world away who have nothing in common with you but their humanity.
