How it's used

Mathematical terms like this are almost exclusively used in academic or technical contexts in Hong Kong. While the concept is simple, the formal term is rarely heard in casual conversation unless discussing geometry or topology. Most people would simply describe the shape by comparing it to a donut or an inner tube.
