Yiduan is a Chinese word that means "one section" or "one segment." It is often used in the context of architecture and design to refer to a specific area or part of a building or space.
Imagine you are playing with some building blocks. You might use different shapes and sizes to create a big house or a tall tower. Now, think about breaking that house or tower into smaller pieces. Yiduan is like one of those smaller pieces. It's a part of the bigger picture.
In the world of architecture, yiduan is used to describe different sections of a building, like the roof, the walls, or even the windows. These different sections all have their own shapes and sizes, and they work together to create the overall look and feel of the building.
When architects design buildings, they often think about yiduan and how each section will fit together. They might make one section really tall to make the building look grand, or they might add lots of windows to let in lots of light. By thinking about yiduan, architects can create buildings that are both beautiful and functional.
