Haha.. Master quickly skipped this question. Hi Jinky, in Classical feng shui, we do not talk about the placement of objects like toads, coins etc. We know which school you are from and we respect that. However, classical fs talks about the landforms and the flow of chi in the exterior and interior of the property. The items at best offer psychological advantages to the occupants in the house but it does not alter the chi in the house. Thanks. Kevin
