The improvement of understanding is for two ends: first, our own increase of knowledge; secondly, to enable us to deliver that knowledge to others.
理解的提高有两个目标:首先,我们自己的知识增长;其次,使我们能够将这些知识传递给他人。
The past is never dead. It's not even past.
Each of us is the author of our own story, though sometimes we cannot control the ending.
