In life, receiving a gift is a pleasant thing, but if the gift is sent incorrectly, it is likely to make people unhappy. Take the bed as an example. Giving a bed is taboo. Folk custom tradition, send money to send a room without sending a bed. Being "sent to bed" by others means relying on others' help all your life, which in itself implies unlucky meaning.
Under normal circumstances, few people will send their beds at wedding banquets. They all gave bedclothes as wedding gifts to wish each other happiness.
