研究明史需要全面理解其独特的社会结构和文化背景。

I'm a musician, not a celebrity.

Innovation is the key to solving the world's most pressing problems.

For me they normally happen, these career crises, often, actually, on a Sunday evening, just as the sun is starting to set, and the gap between my hopes for myself and the reality of my life starts to diverge so painfully that I normally end up weeping into a pillow.

我写作是为了寻找希望。

所以君子严于律己.宽以待人,而平庸的人却宽以待己.严于律人。
