What does it mean that my wife has to spend two stalks and three flowers?

"An empty wife must have two stalks and three flowers" is a sentence that does not conform to language norms and has no clear meaning.

It may be because there are similarities in pronunciation between "wife" and "seven sons", so this sentence may be intercepted from the idiom "seven sons become Jackie Chan", and "two stalks and three flowers" may refer to the form of "dragon".

So this sentence means "one wife and seven children can become Jackie Chan", expressing expectations and wishes for family and career. But because this sentence has no clear meaning, it needs to be used with caution to avoid misunderstanding.
