barbarian
狄 centers on the concept of a barbarian, specifically referring to non-Chinese northern tribes in ancient contexts. It carries a sense of foreignness and lack of civilization from a historical Chinese perspective.
狄 combines 犭 (dog/beast radical) with 火 (fire). Historically, it was used to name northern non-Chinese tribes, likely with a pejorative animal association. The exact reason for the 火 component is uncertain.
A beast-like (犭) person with fire (火) in hand, representing an uncivilized barbarian from the wild northern lands.
For テキ, imagine a barbarian throwing a tech (テキ) gadget into the fire, confused by modern civilization.
