In the eight characters, I often hear a noun "empty broken". What is an empty beer?

A fool is empty. That's a cliche that fortune tellers are afraid to ask questions because they are not sure. Someone asked Mr. Wang, didn't you say that my life is very lucky? Someone just married a wife, but how many wives should I marry? Why not now? Mr. Wang said there was one, but it was empty! Ok, you don't have to work hard! Don't! Sir, I still want to be lucky. Mr. Wang said it would take several years to fill it in, so just wait! Until when? This ..... this secret can't be revealed.
