* A misspelling: Perhaps you meant a similar word, like "Dulang". A Dulang is a large, shallow tray used for serving food, especially in Southeast Asia.
* A regional term: It might be a word used in a specific region or community, but not widely known.
* A made-up word: It could be a fictional term, perhaps from a book or game.
To help me understand what you meant, could you please provide more context? For example:
* Where did you encounter this word? (In a book, online, in conversation?)
* What was the topic of the discussion?
* Do you have any other clues about its meaning?
With more information, I can try to decipher the meaning of "dinulang" for you.
