The correct form is"百年修得同船渡，千年修得共枕眠"。 The direct translation is"It takes a hundred years to stay in a ship together,and it takes a thousand years to sleep on the same bed。" I remember it originated from the Buddhism.It means we meet ,we get to know each other,we date,we get married,all these things are because of fate and destiny.

这句话字面上来说是：修练十年，只有偶遇的机会，一百年才能成为夫妻。实际意思是缘分很值得珍惜。
