672年

I don't have enough context to provide an accurate overview of "672." The context provided only indicates it's a year, but without additional information about what specific event, work, person, or phenomenon you're referring to, I cannot write an accurate 2-sentence explanation that meets your requirement of being based only on provided facts. If you could provide more context about what "672" refers to, I'd be happy to write that overview.
