Our eyes do not show a lack of beauty, but a lack of observation.
世上不是缺少美，而是缺少发现美的眼睛。
Don't pay too much attention on people's appearance.
Try to find out the inner beauty.
If we had no winter, the spring would not be so pleasant;
if we did not sometimes taste of adversity, properity would not be so welcome.
不历寒冬，春天不迷人；不尝艰辛，成功无欣喜。
Only with comparison can we know the difference.
Only when we had lost the thing can we know the value of it.
If there is no winter, we may not appreciate the spring, a gift from nature.
If there is no adversity, we may take everything we have for granted.
Nevertheless, how about the situation if the winter lasts too long, or if you always stay in adversities?
Obviously, life will die out, aspiration as well.
Optimistic? Maybe.
But there are still seeds that can germinate if the spring comes, and there are still a lot of people that can make a comeback even after being defeated many times.
I think I can try again.
