Oh, sorry, I should have offered more background. That sentence was part of a conversation. I was a high school history teacher in China. I was talking the secondary school curriculum with my U.S. friend. He said when he was in high school, most of their history classes was about the history of Europe and North America, and they seldom learnt Asian history. I said the same things happen in China, and all around the world. People tend to learn more about "ourselves" than "others". That was the context of this piece of writing. Thank you for asking Michael :)

What do you mean in first sentence? What is secondary curriculum ? I think you are saying that learning about one's history and culture is part of the standard curriculum in school. You find it interesting but you are also interested in learning about the history and culture of other societies. Is that what you wanted to convey to the reader ?
