What happens when you put the bill under your pillow? Feng Shui

According to geomantic omen, putting things under pillows has little influence on geomantic omen, but some spells have something to do with it, but there is no mention of bills.

Personally, I think it's better to keep the bill in a drawer or another place, because the bill represents payment and checkout, and it always feels bad.

it's better to hang a hundred-treasure gourd on the bedside, which is sold on the internet.

good luck!
