The pots in Zuko’s cabin

So, Zuko really likes pots, huh. I counted more than seven in his cabin. There’s something else I noticed when I took a closer look. Zuko apparently likes to decorate with national treasures. The four pots, one at each corner of his room seem to be neolithic and strong resemble pottery from China’s longshan era.

The Longshan culture ( 龙山文化 pinyin: Lóngshān wénhuà; meaning “Dragon Hill”) was a late Neolithic culture in China, centered on the central and lower Yellow River and dated from about 3000 BC to 2000 BC.

That is so strongly resembles pottery from that era and that said era is name Dragon Hill era makes me think this is not a mere coincidence.

Clothing is folded left over right. Reverse folding indicates death, ghosts or a suicide run.

… or a fucking moron…
