The window faces the stairs.
Stairs are divided into ascending and descending. The window facing the upward stairs will bring wealth to the house, and the wealth above will flow into the house along the stairs.
By the same token, if the window is facing the downward stairs, wealth will also go down the stairs, and residents will lose money at home and work hard to make ends meet. If someone lends you money, be careful not to pay it back.
The solution is to hang a concave mirror on the windowsill to collect the flowing air.
