Dragon and Pig compatibility
Friction
The Dragon is the branch 辰, Yang Earth. The Pig is 亥, Yin Water. Here is how the two branches meet in the tables Korean saju uses, and how their elements relate.
By the tables, the Dragon and the Pig have friction marks and no combination. That reads as a pair that rubs, not one that can’t work: the friction is usually about habits and timing.

Branches: 辰 and 亥
Wonjin (怨嗔)Friction
In Korean saju, 辰 and 亥 are also an old-grudge pair: a mild, on-and-off irritation where small things sting. Korean compatibility readings check it often; it is one mark among many.
Gwimun (鬼門)Friction
辰 and 亥 form a jumpy-nerves pair, a Korean-school reading of heightened sensitivity between two people. Good sleep, steady routines and not reading too much into moods are the usual advice.
Elements: Earth and Water
Earth controls Water in the controlling cycle. The Dragon side tends to set the frame and the Pig side tends to feel it. Read gently it is structure, read harshly it is pressure. Agreeing who decides what usually helps.
辰 is Yang and 亥 is Yin: one of each.
How to read this
A zodiac sign is one character out of eight in a saju chart. For two people, the birth-day pairs, the balance of elements and timing usually say more than the signs do. Treat this page as a tendency, for fun and self-reflection, not a verdict on anyone.
