The word "全盘" is formed by combining the character "全", meaning "whole" or "complete", with "盘", which denotes a "plate" or "tray" but in this context extends metaphorically to represent a "situation" or "scope". Together, they create a compound where "全" modifies "盘" to convey the idea of "overall" or "comprehensive", implying an entire set of circumstances or elements as if viewed as a whole plate.
