What is the Chinese Bone Weight Calculator (Chenggu)?

The Bone Weight Calculator, known as Chenggu, is an ancient Chinese astrological method created by Master Yuan Tiangang during the Tang Dynasty. It assigns a symbolic weight (measured in Liang and Qian) to the year, month, day, and hour of your birth. The sum of these weights determines your total bone weight, which corresponds to a specific destiny poem predicting your lifetime fortune.

Does Heavier Bone Weight Equal Better Fortune?

In Master Yuan's system, bone weights range from 2.1 Liang to 7.2 Liang. While heavier weights generally correspond to more auspicious poems predicting wealth and ease, a lighter bone weight does not doom one to poverty. Many self-made individuals who achieve great success starting from scratch have lighter bone weights, showing that personal choices and efforts shape one's final path.

Frequently Asked Questions (FAQ)

Q: Should I input my solar or lunar calendar birthday?
A: Chenggu bone weight is strictly based on the traditional Chinese lunar calendar. Simply enter your solar (Gregorian) birth date and the system converts it to the correct lunar bone weight automatically.

Q: Does heavier bone weight always mean better fortune?
A: Not necessarily. Bone weights range from 2.1 to 7.2 Liang; heavier weights generally carry more auspicious poems, but destiny values overall harmony — many light-boned charts achieve great success through self-made effort.

Q: What is the relationship between "Liang" and "Qian"?
A: Both are ancient Chinese weight units where 10 Qian equal 1 Liang. The calculation follows base ten (e.g., 3 Liang 8 Qian + 9 Qian = 4 Liang 7 Qian).
