Siheyuan, a traditional Chinese residential structure, is characterized by buildings arranged around a central courtyard. Typically warm in winter and cool in summer, it provides a comfortable living environment particularly suited for extended families. While various types exist across China, the Beijing siheyuan is the most classic example. With modern urban development, traditional siheyuan have gradually diminished in number. However, their unique architectural style remains significant for preserving cultural heritage and historical research on Chinese vernacular architecture.
