"Square five, circle seven" – an ancient Chinese architectural rule of proportion passed down through generations. By simplifying the geometric relationship between a square and its circumscribed circle into ratios like 7:5 or 10:7, ancient Chinese craftsmen distilled profound architectural wisdom into a simple folk saying. Behind these seemingly plain words lies the essence of traditional Chinese aesthetics: harmony, balance, rhythm and the timeless beauty of proportion.

Countless iconic ancient structures embody this classical design philosophy. Though time has passed, these enduring architectural masterpieces continue to captivate visitors from around the world. Today, they have become must-visit destinations for those seeking the charm of traditional Chinese culture and the immersive beauty of ancient Chinese architecture.
