How to see if the Long Mai in your ancestral grave has been exhausted?

This kind of thing is hard to say. If you believe there is one, if you don't believe it, there is none.

But what can I say? It doesn't matter if there is Long Mai in your ancestral grave, does it? Of course, this is not superstition.

Even according to superstition, your ancestral grave is finished in Long Mai. Why do you want to remove it? So you can continue your family's current luck?

This is sheer nonsense.

If you have time to think about these problems, you might as well think about other ways to make money.
