Chinese 地方支援中央A humorous term for when a balding man uses surrounding hair to cover up his bald spot.

Originally a tactical term meaning “regional military traveling in to support the main force”. Now used jokingly to refer to when a balding man keeps the hair on the back and sides long and brushes it over to cover the top of his head. [Example pic](https://imgur.com/a/UOOhh55)
