Hello there! Yes it is correct. It is an english saying. Basically this phrase is used to describe a busy place. If you have seen a beehive before it makes sense why it became a common term :)

An example would be "On fridays, the mall is a hive of activity"

Another similar thing we might say that relates to this is "buzzing with activity" (In english buzz is what we use to describe the sound a bee makes)

Example "on fridays the mall is buzzing with activity"

Good luck! (^｡^)

Hi there Sasha, Maybe I can help you a little. Just as Rami says, it means people are very busy with many tasks. Here are a few examples: - My office is a hive of activity because the CEO will visit us next week. - My school was a hive of activity preparing for our annual homecoming parade. These are typical examples using this expression. I hope that helps you. Keep on learning! Ds3

"A hive of activity refers to many activities happening at the same time but which is organized in nature, like a hive. Which is constantly buzzing and active but every bee has its specific job. A non-chaotic activity hub. A place where people put in a lot of hard work."
