What do you get when you move? The meaning of deer and elephant

People can send a pair of vases for housewarming to show peace; "Send deer" means "send Lu"; "Send an elephant" means "send good luck". If you are an acquaintance with a particularly good relationship at ordinary times, you can directly ask him what he lacks. Most of them can buy kitchen utensils (pots) and household items (bedding, etc. ) as a gift. You can't send teacups and teapots.
