CORE DEFINITION

Vomiting above (rejecting food and drink) and closure below (urine and stool blocked). The yin and yang qi are not connected in sequence, and the upper and lower passages are completely blocked.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Shutdown maintenance signal. This is a dual collapse of the digestive and urinary systems (e.g., end-stage uremia). Because both "closure" and "rejection" exist simultaneously, taking medicine causes vomiting, and excretion is impossible. It is an extremely critical "deadlock" state.

Anchor fast decisions

Closure and Rejection describes a deadlock state of "vomiting above and closure below, yin and yang qi not connected in sequence": the dual channels of input (eating) and output (excretion) are simultaneously blocked. As a thinking model, it metaphorically represents a system at a critical point of collapse where it can neither absorb new resources nor expel waste.

MINIMUM ACTION

In progress 0/4

Practice this model in one real situation:

Identify whether the system has bidirectional blockage of "cannot enter and cannot exit"
Determine whether the input side or the output side fails first
Prioritize opening a single channel to break the deadlock
After recovery, address the root cause to prevent recurrence.
