The word 中西合璧 is formed by combining 中西, meaning "Chinese and Western", with 合璧, meaning "to combine harmoniously". 中 represents Chinese elements, 西 represents Western elements, 合 means "to combine", and 璧, originally referring to a jade disc, here functions within 合璧 to denote a seamless fusion. Thus, the word directly constructs the concept of blending Chinese and Western elements into a cohesive whole.
