2. In fact, in ancient China, people always liked to associate plants with marriage. For example, in the Book of Songs, a man who is about to get married said when he was preparing to decorate his new house: "I sprinkled lotus leaves on the roof and hung calamus and Malan on the wall; Let the mint smell pervade the courtyard, and the beams are made of camphor; There are bayberry leaves on the wall, magnolia on the door, peony on the roof, and all kinds of vines are wound into curtains. The ground is covered with grass blankets, and magnolia is hung on the mat; Orchids are fragrant, hazelnuts and lotus flowers are intertwined, irises and lilies set each other off, and flowers are in full bloom in the garden.
It is worth reminding that green plants are still huge "carbon-absorbing oxygen plants". Green leaves of plants absorb carbon dioxide in the air, react with water absorbed by plants under the action of sunlight and chlorophyll to generate glucose, and release oxygen at the same time, and then glucose molecules form starch. Therefore, putting some green plants indoors, such as abundant bamboo and trees, not only symbolizes the vitality of marriage, but also creates fresh oxygen, which is of great benefit to health.
