If u invite 'sifu' come see now, they 'probably' charge u or ask u buy something to change ur windwater.
If u don't listen and when things happen, so called 'sifu' will come and 马后炮 say ur windwater got issue but u no listen
If u dont listen and nth happen, to them its just 时辰未到
If u listen and nth happen, then the 'sifu' will be proud to say its thier effort
If u listen and something happen, then 'sifu' will say 煞气严重, need u do more windwater thing

Well, its easy, if u are rich, u r the fengshui role model to be followed.
One day u from rich become bankrupt, u will also be a role model.
