The expression Yike Yin is often explained through the compact, seal-like outline of a courtyard dwelling. A description published by Yunnan’s publicity network names the main house, side rooms and a roofed gate as parts that enclose a central court. The court is not leftover space between rooms. It is the shared centre that makes light, movement and household encounters possible.
The same account describes differences in scale and arrangement, from modest houses to larger compounds with extra courts and galleries. Courtyard architecture includes a range of sizes and layouts, with rooms and open spaces combined in different ways.
