Sách thực liệu bảo kiện, chia các mục như Thực nghi, Nguyệt kỵ. Kết hợp cấm kỵ theo tháng với nguyên tắc ăn uống của người tu chân, thuộc dòng dưỡng tính–thực dưỡng trong Đạo tạng.
Ứng dụng: Tra cứu thực liệu, cấm kỵ tháng và bảo kiện theo lối đạo gia.
A yangsheng/Neidan-adjacent 'secret record of cultivating perfection' associated with Fu Du (傅度) or related Tang–Song compilers (editions vary in catalogues). It collects methods for refining the body-spirit: breathing, dietary avoidance, minor elixir tips, and warnings about leakage of essence. Sits on the continuum between medical nourishing-life texts and early internal alchemy; often cited in Daoist bibliographic notes as a practical xiuzhen digest.
⚡ Ứng dụng: Essence conservation and seasonal practice reinforce BaZi counsel on protecting weak water/wood or controlling excessive fire/metal.

It proves that 'cultivating perfection' is a secret sequential craft: without ordered steps and concealed keys, scattered longevity tips never cohere into 真. Secrecy protects sequence integrity.
1) Build a staged curriculum (form → breath → spirit) with clear gates. 2) Hide advanced fire phases until lower gates stabilize. 3) Use BaZi to time stage transitions (e.g., strong Fire years for cautious firing). 4) Keep a private practice log—the modern 祕錄. 5) Test one variable at a time.
More sequential-esoteric than 混俗頤生錄's open lifestyle advice; less single-pointed than 碧虛子直指. Bridges medical yangsheng and full neidan without being pure liturgy.
