Hi BaziLearner,

This is just my rudimental guess...

If you follow JY, Surging Snake in Xun palace can denote Flower spirit or Snake spirit which usually will live harmonious with their surroundings. There is a traveling horse in this palace, which may denote things that move around a bit.
Surging Snake is the master of the environment. Can be cunning, shrewd, likes to manipulate others and its environment.
There is a hidden Six Crescent Punishment in this palace. So maybe things may get unusually.

Your stem is Ding (fire) which sits in the Dui palace. It holds the Hook (Gou Chen) deity. Not an auspicious deity, but has good qualities. Within your context, Hook denotes having to do with what is old, antique, history / historic. Possibly associated with past lives, past knowledge.
