This paper compares the

（《周易》） from three dimensions of "time， position， and virtue"， aiming to reveal the penetration of

thought in the formation of the doctrine of five evolutive phases and six climate factors and its own theoretical transformation. Both the "doctrine" and the "book" centered on "time"， recognizing temporal order through observation of celestial phenomena and calendar formulation.

The Book of Changes

emphasizes "seizing the timely moment" to master the principles of change in all things， while doctrine of five evolutive phases and six climate factors focuses on "understanding time" to clarify how

qi

relates to temporal phases. Regarding position， both treat it as time-derived and philosophically significant within a six-tier structure. The

The Book of Changes

uses

yao

（爻） positions for judging auspiciousness， inauspiciousness， regret and distress， with such judgement permeating the overall structure of the hexagram； the doctrine of five evolutive phases and six climate factors uses

qi

positions， where "

dangwei

（当位）" denotes normative

qi

transformation governing the overall pattern. Both hold that "virtue" arises from time‑position harmony， representing conformity to time and suitability to position. In

The Book of Changes，

"virtue" serves to encapsulate the attributes of things and the principles of heaven and earth， whereas the doctrine of five evolutive phases and six climate factors furhter extends "virtue" to denote the normative state of

qi

transformation. Thus， the intellectural structure of time， position and virtue in the doctrine of five evolutive phases and six climate factors was influenced by Yijing scholarship， within which it completed its theoretical evolution distinctly.
