What does it mean for monkeys to make money from parties?

It means that monkeys represent wealth and will bring you wealth.

Monkeys are golden life, saying that people who belong to monkeys are rich and prosperous. At least two of them live a rich life, so they are born with good brains and wisdom. If they were born in September of the lunar calendar, they would be favored by the god of wealth. Born as a "fruit-eating monkey", he was born in the golden autumn of September in the lunar calendar and ate well. He has been rich since he was a child, and he must be loved by his parents and clan from birth. He leads a stable life and has money to spend every year. Either he has a successful career or he can enjoy the happiness of the other half. He was born happy!
