There should be as few things on the table as possible. Small potted plants, pen containers and mascots should be placed on the left hand side, with less things on the right hand side, or with low objects.
Curtains should be added in bedrooms and study rooms to prevent evil wind from harming the body: cloth or bead curtains should be hung on the doors of bedrooms and study rooms for the elderly to prevent evil wind from harming the body when the elderly unconsciously doze off. It's summer now, and many people have the habit of gluttony, which is actually not good. It's hot in summer, so you should open people's pores to dissipate heat.

Sea melon represents blue in color and should be avoided in many occasions. For example, many elderly people drive nightlight in their bedrooms for fear of not letting their young grandchildren sleep. Then, instead of blue light, nightlight should use ordinary yellow light. Scientifically speaking, blue gives people a cold feeling, and children will feel horrible and gloomy. In geomantic omen, hexagrams represent the southeast, which is in charge of reading, so it is best to put the study in the southeast of the house. Scientifically speaking, the sunny southeast will make people feel happy and suitable for reading. Feng Shui also believes that if the toilet is located in the southeast of the house, or there is a shortage in the southeast of the house, it will have an adverse impact on the marriage and career of the eldest daughter, or the children at home don't like reading, then green plants can be placed in the southeast to solve it.
Gua also represents smell. Feng Shui believes that the fresh air in the home will make the yang strong. Therefore, it is necessary to open the window often to breathe, keep the sewer at home unblocked, and avoid blocking and emitting odor. Of course, these are all based on science, and a life without peculiar smell is beneficial to human health.
