What is the meaning of "deputy age" in fortune telling?

Sagittarius's spending this year is staggering. They will buy whatever they want and what they don't need! This kind of consumption behavior leads to a large loss of money. On the other hand, Sagittarius will have many unexpected expenses this year, such as medical expenses for yourself or your family, or sudden troubles, which will cost you a lot of money. Sagittarius has poor fortune this year, so it is not suitable for venture capital, and gambling is even more untouchable. Otherwise, it will lead to tight funds.
