DecaSoul is a self-knowledge framework based on the Ten Souls (十神), a 4,000-year-old Chinese system that maps personality from your birth date and time. Take a free two-minute test at www.decasoul.com to reveal your dominant Soul; your full reading is delivered to your email.

Is the Ten Souls system the same as astrology or MBTI?

It is distinct. Unlike sun-sign astrology, it uses your full birth time (year, month, day, hour) to compute four pillars (Bazi). Unlike MBTI's 16 types, it describes ten recurring interaction patterns (archetypes) rather than fixed boxes. DecaSoul frames it as a reflection tool, not a prediction.

Bazi vs Systems

Zi Wei Dou Shu vs Bazi

Zi Wei Dou Shu (紫微斗数) is a Chinese astrology system that maps stars into twelve palaces from your birth time. Bazi (八字) computes the Four Pillars — Heavenly Stems and Earthly Branches — and derives the Ten Souls (十神).

Zi Wei Dou Shu is star-and-palace based (complex, 100+ symbols); Bazi is element-and-pillar based (simpler, ten archetypes). Both are Chinese, but Bazi's Ten Souls map more directly onto a modern personality framework.

Two Chinese systems, two goals

Zi Wei Dou Shu is a detailed chart of life domains (wealth, career, relationships) through stars and palaces. Bazi's Ten Souls read more like a personality framework — which is why DecaSoul built the 东方MBTI on Bazi rather than Zi Wei Dou Shu.

Frequently asked

Is Zi Wei Dou Shu more accurate than Bazi?

They serve different purposes. Zi Wei Dou Shu gives a detailed life-domain chart; Bazi's Ten Souls map directly to personality, which is why the 东方MBTI uses Bazi.

Which should a beginner start with?

Bazi's Ten Souls. It has a flatter learning curve — ten archetypes versus Zi Wei Dou Shu's hundred-plus symbols.
