Notes
When using 界 to describe fields or domains, it often follows a noun indicating the area, forming a compound noun. It is a formal term and common in written and spoken Chinese when discussing boundaries or sectors. Avoid confusing 界 with 边 (biān), which more often refers to edges or sides rather than conceptual boundaries.
