Neijing Life Curve

POST/api/v1/chinese/bazi/lifespan

Generates a personalized energy trajectory (Jing, Qi, Shen) across a full lifespan (0-120 years). Based on the Yellow Emperor's Classic of Internal Medicine (Neijing Suwen) cycles and BaZi luck pillar modifiers.

Endpoint Capabilities

Dual Jing Pools

Differentiates between inherited Prenatal Integrity and acquired Postnatal buffer

Qi Duality

Tracks Pre-Heaven Yuan Qi (innate flow) vs Post-Heaven metabolic energy

Prenatal Leakage

Simulates how poor lifestyle choices and bad luck drain your original life reservoir

Neigong Modulation

Use the cultivation_factor to simulate how practice and attention preserve structural integrity

Shen Coherence

Mental clarity derived from the stability of the Pre/Post-Heaven energy field
