对知识的追求是无止境的，而这正是它令人兴奋的地方。
The pursuit of knowledge is endless, and that’s what makes it exciting.
"Books are the quietest and most constant of friends; they are the most accessible and wisest of counselors, and the most patient of teachers."
Survival can be summed up in three words – never give up. That’s the heart of it really. Just keep trying.
