(1) Landscape painting pays more attention to "the mountain owner decides the water and the main wealth". If there is a landscape painting hanging in the hall, it is necessary to observe that its water potential flows into the house and cannot flow out. Water inflow is money, and water outflow is money loss; Draw a boat with the bow facing inward, and avoid facing outward, because those facing outward will lose money and those facing inward will make money.
(2) The calligraphy and painting above the sofa should be horizontal and not straight. If sofa and calligraphy and painting form two balanced horizontal lines, they can complement each other. Calligraphy works should not be hung on the sofa, which means "memorizing words".
(3) Try not to hang figure paintings in private places such as bedrooms and bathrooms, and beware of "little people" at home.
(4) Images with too much color or black bring a heavy feeling to the viewer, which makes people depressed and pessimistic.
