What does it mean to sign a poem?

This poem is the signature of the lottery, and its meaning is as follows:

The spirit of the family is refreshing: winning this symbol is now a symbol of family prosperity, children's prosperity and their own spirit.

With the help of nobles, fame and fortune are easy to gain. For me, the sun, moon and stars are auspicious, the sun, moon and stars are scarce, and the moonlight is like water.

Women are lonely: but winning this constellation is not good for women. Either the middle-aged and elderly women are widowed and lonely at present, or they are lonely and unlucky. Young women are worried about marriage and love, and it is difficult for them to conform to the image of a desirable love object.

A man is the richest man in the world: the man who gets this symbol is either the richest man in the world at present or has the opportunity to become rich one day.
