Waaa.....Felix, don't have to be so worked up leh!!! A practitioner shouldn't sound like that especially to a lady leh! This is very sarcastic and rubbing salt to the wound.
As a matter of fact, I think she's quite right. Last time heard from few masters that 'san he' and the etc etc water method not accurate leh. Well, I thought you quite open, that's why I ask and share, if you gonna get worked up again, I'll be disappointed.
I heard from other masters that if water placed wrongly, sometimes can be so bad that accident happen or can see blood leh. I hope those people you try didn't involve much with water placement.
Anyway, if you know water method, you should know the chinese phase that Ivy wrote? Don't you?
