are the two the same or not, thanks..

Not quite.
She worked very hard around the clock. = She worked night and day without sleeping.

She was working as busy as a bee. = She was very busy. (We see bees and they are always working very hard. They do rest at night, though.)

Thanks a lot my mentor, then, both are not the sentence I am looking for I wanted to mean something like this;
"I had worked very hard even without a minute to rest four hours straight, I was so busy that even bees can't be matched to mine efforts. By noon, I was exhausted."
That is what I meant with busy. Thanks

osmancatalolukNeither is the sentence I am looking for.

She worked very hard around the clock. (Your original.)
Are you a girl or woman?

How about this?
I had worked so hard, four hours straight without a minute's rest, that, by noon, I was exhausted .

The original she was my mother; the others are just the example of the sentences I made. Thanks a lot. I am not a girl am a man and she was my mother I mentioned about while I was making this sentence (an example).
But you've changed both to neither, which surprised me. Is it because both refers to positive and neither refers to negativity?

osmancatalolukIs it because both refers to positive and neither refers to negativity?

Exactly right. These say the same thing.

Both of them are incorrect.
Neither of them is correct.

thank a lot
