INTRODUCTION

English translation pending.

CORE DEFINITION

Dry blood (Gan Xue) is a concept in traditional Chinese medicine describing blood stasis that has stagnated so long that its fluids are exhausted, leaving it dry, hard, and immobile. It is associated with the dry-blood wasting pattern, in which failure of blood to nourish the tissues produces rough, scaly skin and amenorrhea, and it is treated with formulas such as Dahuang Zhechong Wan, which use insect drugs to break up the mass. In forensic usage the term denotes already coagulated bloodstains. As a thinking model it names any residue that has lost its activity.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Stasis audit: classify old resources as flowing blood or as hardened, immobile dry blood. - Tool match: use renewal and clearing for dry blood rather than simply adding more supply. - Trace reading: treat dry blood as a settled mark that records a past event rather than a live process.

Anchor fast decisions

Fresh stasis behaves like mud: it still holds fluid and can be washed away by blood-invigorating treatment. As fluids evaporate over time, the same material hardens into something cement-like, and ordinary invigorating drugs can no longer move it. Breaking it up requires agents that physically disintegrate the mass, which is why the classical response escalates from herbs to insect drugs. Stagnation left long enough changes kind, not just degree.

Glass Walls

Distinct from the 'glass ceiling' (vertical promotion barrier), it refers to women or minority groups being isolated in certain functional departments (e.g., HR, administration), making it difficult to move laterally to core business departments (e.g., sales, R&D), thereby lacking the key experience needed for promotion.

Inertia

Inertia is the natural tendency of objects in motion to stay in motion and objects at rest to stay at rest, unless a force causes its velocity to change. It is one of the fundamental principles in classical physics, and is described by Isaac Newton in his first law of motion (also known as The Principle of Inertia). It is one of the primary manifestations of mass, one of the core quantitative properties of physical systems.
