There may be a misunderstanding or misspelling in your question. "Hangong Chad" does not have a known meaning or significance. If you can provide more context or clarify the question, I'd be happy to help further.

In the 2000 election, the Florida ballot machines were said to have malfunctioned. A hanging Chad refers to the paper ballot that looks like it was pressed enough to tear but did not punch out completely.

a piece of paper that is supposed to be removed after having a whole be punched in it

The ballots that produced the handing chads were paper tabulating machine cards, commonly called IBM cards or computer cards. The voter was supposed to punch out a perforated tab or chad to make his vote. The chad was supposed to be completely removed to create a clean hole in the card, but some people punched the card, but left the chad hanging. These hanging chads interfered with the machine used to read and tabulate the vote cards.

The anagram is Chad, a country in central Africa. It also is a problem in the Florida presidential election (hanging chads).
