"西洋" (Xiyang) refers to the Western world, primarily encompassing countries in Europe and the Americas. It is often contrasted with "东方" (Dongfang), which means the Eastern world, including regions like Asia. The term is used in various contexts, including culture, politics, and economics, to describe influences and interactions between these two broad areas. Historically, "西洋" has been associated with the spread of Western culture, technology, and ideologies, particularly during the age of exploration and colonialism. This influence has shaped global dynamics, leading to significant exchanges in art, science, and philosophy, impacting figures such as 牛顿 (Newton) and 达尔文 (Darwin).
