There is a saying in Guangdong that "the pig cage goes into the water-I can bask in silver paper (there is more money than I can spend)". I don't know how to explain this "pig cage into the water".
I'm from Guangdong, which means making money. Water is called money, old water means 100 yuan, water means money, or he has money, or rice means he has money. It's a Cantonese idiom. For example, if a person is doing business, business is good, and your pigsty is flooded.
