Translation of "Grief" in Chinese

She was filled with deep grief to hear of her father's sudden death.

她得知父親突然離世，不禁心如刀割。

I applied my heart to know wisdom, and to know madness and folly. I perceived that this also was a chasing after wind. For in much wisdom is much grief; and he who increases knowledge increases sorrow.

我一心追求智識，也了解了瘋狂與愚蠢。我覺得這就像是追著風跑。智識的背後是傷悲，所以追求智識之人也多了幾分悲傷。
