Forward and Reverse Sixty Shou: Qi Transformation Is a Path, Not a Static Table

The Mirror Classic of Bian Que does not simply list the “Sixty Shou.” It explicitly says:

The Upper Classic of Shennong says: the forward and reverse Sixty Shou.

It then presents two large sequences.

The first begins “An-Huangzhong, Fu-Dalü, Gong-Taicu, Ge-Jiazhong…” and continues in one direction. A later sequence begins “He-Huangzhong, An-Yingzhong, Fu-Wushe, Gong-Nanlü…” and unfolds differently.

This reveals a crucial point: the Sixty Shou are not merely a classification table; they are sequences.

The same state can mean something different depending on the direction of approach

If we know only that the current state is An-Huangzhong, we know a position. If we also know where it came from and where it is going next, we gain directional information.

Ascent, descent, entry, and exit in qi transformation are inherently directional. The same numerical state appearing during ascent and descent need not mean exactly the same thing.

The forward and reverse Sixty Shou therefore tell us that a state must be understood within a path.

“Qi ends and the manifestation changes” marks a transition

At the end of one part of the forward sequence, the text says that “qi ends and the manifestation changes.”

The sequence does not simply stop; the manifestation changes and another mode of operation begins.

The reverse sequence is concluded with language of “becoming gently harmonious and separating from one another.” These expressions likewise show that the Sixty Shou describe transformations between states, not fixed boxes.

This connects directly with later “shifts”

The Eight She and Kuidu repeatedly use terms such as shift, return, hidden alternation, entanglement, and repeated movement. Without the forward and reverse sequences, these can sound like abstract philosophy.

Placed back into the Sixty Shou, however, they describe something more specific: qi-transformational states deviate, return, or reverse along an ordered sequence.

A practical way to read the large classical tables

When encountering a long ancient arrangement, do not ask only “what does each symbol mean?” Ask three additional questions:

1. What state comes immediately before it?
2. What state comes immediately after it?
3. Is this section moving forward, moving in reverse, or undergoing a change of manifestation?

These questions turn a static code table into a dynamic route.
