The importance of geomantic omen in restaurants and kitchens?

According to Zhou Yi's theory, it is not good for the kitchen and dining room to be feng shui together. The kitchen is fire, the dining room is water, and fire and water collide. The design of modern real estate cannot be changed. It can be separated by decoration, and the partition wall is tiled. There'd better be flowers and fruits in the tile. The reason is that huaguo belongs to wood, aquatic wood, and wood makes a fire, which means Wang Dingcai.
