What is Bone Weight Fortune Telling?

袁天罡 · 约公元650年

Bone Weight Fortune Telling (称骨算命) is attributed to Yuan Tiangang, one of the most renowned diviners of the Tang dynasty (circa 7th century). Yuan was an expert in astronomy, calendrical science, and physiognomy, and co-authored the famous Tui Bei Tu (推背图) prophecy text with Li Chunfeng. The Bone Weight system is his most widely practiced legacy — its simplicity requires no specialized knowledge, making it accessible to anyone.

The method assigns a weight value (measured in 'liang' and 'qian', traditional Chinese weight units) to each component of one's birth date: year, month, day, and hour. The four values are summed to produce a total bone weight. Ranging from the lightest at 2 liang 1 qian to the heaviest at 7 liang 2 qian, there are 51 distinct weight levels. Each level corresponds to a four-line destiny poem that metaphorically describes the trajectory of that fate — from youth through middle age to old age.

Unlike the more granular Eight Characters (Ba Zi) system, Bone Weight Fortune Telling groups all people into just 51 categories, making it a broader folk wisdom rather than precision divination. While its scientific validity cannot be verified, it remains a classic system of traditional Chinese fate philosophy, embodying how ancient people conceptualized destiny. This site presents representative weight levels with original poems and vernacular interpretations.
