Complete Chinese saying which title comes from?

The Chinese saying is: “Xiu bai shi ke tong zhou, xiu qian shi ke tong zhen.”

It's translated in the scene where Yilan tells her Russian lover that they cannot be married as: "It takes [100] years of prayers to cross a river in a boat with someone; It takes [1000] years of prayers to share a pillow with someone." There is also a voice-over at the beginning where Mr. Shi refers to an old Chinese saying and says: "it takes 1000 years of good prayers for a father and daughter to get along".

Just saw this flick a few days ago. Lovely and poignant story.

The full proverb is: "It takes three thousand years of good prayers to lay your head side by side with your loved ones on the pillow, for father and daughter a thousand years, maybe"Source:Movie Reviews - A Thousand Years Of Good Prayershttp://moviereviews.noskram.com/2009/09/movie-reviews-for-a-thousand-y ears-of-good-prayers
