About Rain umberlla
An umbrella is a portable, hand-held device designed to protect against rain or sunlight (parasol), featuring a foldable canopy made of fabric or plastic supported by metal/wooden ribs on a central pole. Originating as a shade tool in ancient China and Egypt, modern umbrellas serve as common, stylish accessories and, in some contexts, as an organization "umbrella" representing a collective group.
