INTRODUCTION

English translation pending.

CORE DEFINITION

Fish swimming pulse is one of the seven failing pulses in Chinese medicine. The beat is extremely weak, its head fixed while its tail wavers, resembling a fish swimming at the surface of water that sinks out of sight and then returns. It signals that true yang is declining and stomach qi is nearing exhaustion, so yang floats at the surface with its renal root already cut. The image of a dying fish turning belly up captures the last wavering before the pulse disappears.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Root test: read a fixed head with a wavering tail as evidence that the support below has failed - Surface drift: treat yang floating at the exterior as a sign of separation rather than vitality - Differential work: distinguish this image from shrimp swimming and boiling cauldron pulses by their motion

anchor

Anchor fast decisions

Yang qi normally circulates at the surface while remaining anchored in the lower body. When the root gives way, surface yang has no base, so the beat becomes extremely weak and wavers in shape rather than in rhythm. The fixed head shows that some structure remains, while the wavering tail shows that the underlying support is gone. Because the loss sits at the root rather than in the surface channel, treatment must restore the base instead of chasing the surface motion.
