50 Yuan Shang Yang Fang Sheng

Shang Yang's reforms of the 4th century BC — abolishing hereditary privilege, reorganizing the army by merit, and restructuring land tenure — transformed the Qin state from a peripheral power into the administrative machine that would eventually unify China under the First Emperor. The fang sheng form referenced in this coin's name is an ancient jade object whose interlocking diamond geometry carried associations with nobility and cosmic order, making it a recurring motif in Chinese decorative arts for over two millennia.
