A square layout has regular walls and high space efficiency — furniture fits, waste is low. More importantly, circulation: in a square plan the path from bedroom to living room to kitchen is short and straight, easy for daily movement. Irregular layouts easily create hard-to-use corner spaces; these "dead corners" quietly accumulate visual noise, making people subconsciously feel "something is off."
Square and regular: usable and easy to furnish, less psychological awkwardness.
Light and ventilation: north-south transparency aids airflow; daylight directly affects mood and rhythm — the hardest-core "energy" of a layout.
Dynamic-static zoning: separating bedroom (quiet) from living/kitchen/bath (active) reduces mutual disturbance.
Storage space: enough storage keeps life orderly; order itself lowers anxiety.
Tradition says missing corners are inauspicious; the modern reading is simpler: a missing corner often means a function zone is compressed. A small northwest corner may just mean less storage or study space; a missing southeast may limit living comfort. Rather than panic over "bad position," see which life function it affects, then compensate with layout — add a lamp, a cabinet, adjust furniture facing. That is more practical than any talisman.
North-south transparency is not just a marketing phrase. Airflow lowers indoor pollutants and humidity; daylight shapes wake-sleep rhythm through the circadian cycle. A long-dark, stuffy home easily drags mood down — fully consistent with science; the ancients just summarized it as "energy."
① Prioritize square, regular forms. Livable beats "special."
② Check light and ventilation in person. Visit at different times, not just the model unit.
③ Mind dynamic-static zoning. Keep the master bedroom away from the entrance and kitchen.
④ Leave storage margin. Stuff only grows over time.
On XinYou, you can use the luopan tool to measure the home's facing, then the Xuan Kong Flying Stars chart to analyze the spatial pattern, turning the feeling of "square and transparent" into referenceable coordinates.
