Hi there, little one! Do you know what a book is? Yes? Well, Samguk Sagi is a book that tells us about the history of three kingdoms in Korea a long, long time ago.
So, many, many years ago, before you or I were born, there were three different places in Korea - Silla, Baekje, and Goguryeo. The people who lived in these kingdoms had different cultures and beliefs, and sometimes they would fight with each other.
Samguk Sagi is a book that was written a long time ago by people who wanted to remember what happened in these kingdoms. It tells us stories about the kings and queens who ruled, the battles they fought, and the traditions they had.
It's like a big storybook with lots of pictures and words. But instead of made-up stories, it's about real people who lived a long time ago.
The people who wrote Samguk Sagi wanted to make sure that we don't forget about the history of these kingdoms. They wanted to make sure that we remember the bravery and struggles of the people who lived there.
And that's what Samguk Sagi is - a book that helps us learn about the history of Korea from a long, long time ago.
