CORE DEFINITION

Lung and kidney yin deficiency, with exhaustion of body fluids, leads to hoarseness (chronic hoarseness). Like a broken bell, the sound it makes is broken.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Casting work. Professional voice users (teachers/singers) often have hoarseness of this type. There is no obstruction; the vocal cords (metal) are worn. Treatment should nourish yin and moisten the lungs (repair the bell wall), not use clearing agents (which would further damage).

In traditional Chinese medicine, the lung corresponds to metal. 'Broken metal does not ring' refers to deficiency of lung qi and yin, leading to loss of nourishment of the vocal tract and resulting in hoarseness or loss of voice. It is a deficiency pattern, as opposed to 'solid metal does not ring'.

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.
