'chinese dynasty ruled totally in disorder' is the definition.
I can't judge whether this defines the answer.

'chinese dynasty ruled' is the wordplay.
'chinese dynasty' becomes 'tang' (I've seen this before).
'ruled' becomes 'led' (I've seen this in other clues).
'tang'+'led'='TANGLED'

Can you help me to learn more?

(Other definitions for tangled that I've seen before include "Knotted" , "Confusedly twisted" , "Twisted into confused mass" , "Complex" , "Muddled together, complicated" .)

I've seen this clue in The Globe and Mail.
