Horse and Pig
These are traditional rules about the twelve signs. No chart decides a relationship.
The traditional relations
- 無 No listed relation
None of the classical relations apply to this pair.
What tradition says
Between 午 and 亥 the tables list nothing. Five places apart, they lie one step from being opposite, and 亥 is the neighbor of 子, the true opposite of 午. 午 is yang fire and 亥 is yin water, and water quenches fire. In the month order one falls in midsummer and the other opens winter.
Stories in popular zodiac books tell of a Horse always heading somewhere and a Pig happy to stay and eat well, and popular charts often describe the two as friendly. That friendliness is a modern impression, and the classical material offers no comment.
One sign is said to go out and the other to settle in. What does a good evening look like for each of you, and how often can both versions happen?
Water quenching fire is a line about the signs 亥 and 午, which does not reach as far as any Horse or Pig who happen to care for one another.
