2. Flowers are commonly used feng shui items, but few people put them in restaurants. If you want to make money, you can put a bunch of carnations in the restaurant, of which yellow and orange are the best, followed by white and red. Because carnations are mother's flowers, placing carnations in the restaurant means thanking mother for her hard cooking.
Putting fish tanks in restaurants is also a way to make money. But pay attention to the orientation when placing. Because the fish tank can't be placed in an auspicious position, let alone a financial position. If the restaurant itself commits the crime of horns, you can put the fish tank in the corner, which can turn horns into water, and water is wealth. Thirdly, it is best to keep an odd number of fish in a fish tank, because in Feng Shui, odd numbers represent masculine and even numbers represent feminine.
