We have just finished our national holiday which occurred from Oct 1st to the 7th. On most of those days I did not teach. I have enjoyed these days off very much. If I understand correctly, you had to teach some days during the holiday, is that right?

We just finished our National holiday from Oct 1st to 7th, Most of the days I don't teach, I have enjoyed these days off very much. It sounds grammatically correct, but logically there are some questions. If it is a National holiday why would you teach any of these days? In USA we would not teach any days of the holiday. Maybe it is different in China. Yes, it is probably not how a USA citizen would say it, but so what? You are not a USA citizen, so it should not matter if you are not one.

Can you write in Chinese because I don't quite understand your intent.
