Case 1 : control in, same element and produce in will enhance Qi. control out
and produce out weaken Qi. water star 4 annual star 8 is "control in" no need
fire.
Case 2: as in case 1: same element enhance Qi. 5/8 now it depends on
what you want.
Yes, but I usuaaly not recommend small Taichi. I got a client which
have 5 rooms, 1 dining room and 2 living rooms. Each room, his master
asked him to put two clocks. Total 16 clock and have to make sure they are all
working. Feng Shui is to help peoples and if this is the case I will say let
Feng Shui go his own way.
