Restaurants are places that provide catering services for consumers, with dense population and great mobility. Paint and furniture used in restaurant decoration will release a lot of harmful gases. Feng Shui believes that it is suitable to put large green plants that can purify the air in restaurants. Through photosynthesis, carbon dioxide is absorbed and oxygen is released, which makes the closed dining environment more refreshing. Especially for urban white-collar workers who sit in front of computers for a long time, breathing more fresh air can make them refreshed and improve their work efficiency and quality of life.

When the restaurant is decorated, green plants should have the function of absorbing harmful gases such as formaldehyde. For example, ivy can effectively absorb benzene pollution, chlorophytum can effectively absorb formaldehyde, evergreen, Nostoc flagelliforme and Ficus can absorb toxic gases to purify the air, and chrysanthemum can absorb hydrogen fluoride. The radiation released by some modern equipment and building materials in the restaurant is harmful to human body, so some radiation-proof green plants can be placed. Planting some plants such as cactus, gem flower and Sedum can effectively reduce the electromagnetic radiation pollution caused by various electrical and electronic products.

When the restaurant is decorated, the best place to put green plants is the balcony, because the balcony is sunny, ventilated and ventilated smoothly, or in the corner near the sun. It should be noted that some large potted plants should be placed out of the way to keep the roads clear.

Placing green plants in restaurant decoration can not only purify the environment but also benefit consumers' physical and mental health, which is one of the necessary decoration strategies for restaurant operators at present.
