Meaning: Longitude and latitude
How to Understand
经纬
经纬 refers to the geographic coordinates of longitude and latitude. It is also used metaphorically to mean the framework or principles that guide something, such as a system or structure.
The character 经 (jīng) originally meant 'silk thread' and later came to represent the north-south lines of longitude. 纬 (wěi) means 'weave' and refers to the east-west lines of latitude. Together, they form a term that literally describes the grid of the Earth's surface.
经纬 is commonly used in geography, navigation, and planning. It can also be found in expressions like 经纬度 (jīngwěidù), meaning 'longitude and latitude.' In a more abstract sense, it may refer to the underlying structure or principles of a system or idea.
