At the first 9 o'clock of the wedding (or the wedding point), what happened to saying it was an empty wedding?

In fact, there are two sayings left over from the past years. 9 o'clock is called an empty marriage' one means that the marriage is not long'. The essence is that lovers may oppose each other, which is empty' as long as it is empty, it is marriage' and then marriage is marriage'. I wish you lovers all get married.
