What does the fairy family mean when they say that the national treasury will leak money even if it has no money?

Xianjia said that if the national treasury has no money, you will make money, but you can't save money. You mean either storing grain in the warehouse or making a lot of money, but you can't save it.

In fact, don't believe what fortune tellers say. These are all fake. You have a lot of money, but you can't save it. If you want to save it in the future, it means that what he said is false, not true.
