What's the point of putting Feng Shui on a rectangular dining table?

From the position: don't face the door at the dining table. If it is really unavoidable, you can cover it with a porch or screen to prevent users from directly facing the dining table. Don't face the toilet door at the dining table. In order to avoid the filthy Yin Qi gathered in the toilet, it will enter the body when people eat, which will affect human health. If it can't be removed, it's best to put a small water dish in the middle of the dining table and soak the iron tree head or bamboo to dissolve it. Don't aim the table at the altar. Yin and Yang are different, so the table where mortals eat should not be too close to the altar. If you worship Guanyin, Buddha and other gods who abstain from killing and are vegetarian, it will be out of place with a vegetarian table. Avoid the top beam on the dining table. The roof above the dining table should be flat and flawless. If there are beams or stairs or sloping roofs, it will damage the health of family members and make the house restless. If there is a beam top or a bald top, it is best to remove the dining table or use a ceiling to make up for it; If the dining table is under the stairs, you can put two pots of bamboo under the stairs to dissolve it. There should be no white candle chandeliers on the dining table. The white candle is a symbol of the funeral. Some chandeliers are made up of several white candle-shaped tubes. Although the design is novel, it is unlucky to hang above the dining table and should be avoided as much as possible. Other colors don't matter.
