The term ‘fan yao‘ – literally, the ‘reverse line’ – was coined by Bradford Hatcher to describe the line that ‘reverses’ the change of a single changing line. (For instance, 1.3 changes to 10, and 10.3 changes to 1: 10.3 and 1.3 are one another’s fan yao.)
The fan yao can be helpful on its own, though it’s best understood as part of a pathway of four related lines including your changing line, for a deep exploration of its themes and resonances. There’s a short course on line pathways inside Change Circle, including…
- An introduction to the four lines of the pathway and how to find them.
- An explanation of the fan yao and how to use it in readings
- …and the qian yao or ‘paired line’
- …and the ‘hidden line’ that completes the pathway.
- An alternative pathway you can follow when your cast hexagram is in a complementary pair.
- An example ‘walk’ round a complete line pathway.
It’ll get you started including line pathways in your own ‘deep dive’ readings. But here’s Module 2 from the course for you now, as a taster, about the fan yao –
