Well hello there little one! Let's talk about poetry in the 9th century. So, a long long time ago, people didn't have TV or phones or computers like we do now. Instead, they had something called poetry. Poetry is like a special way of talking where you use pretty words and make them sound nice when you say them.
During the 9th century, lots of different people were writing poetry in different places around the world. Some people were writing in a language called Old English, which is kind of like a really old version of what we speak today. Other people were writing in other languages like Arabic and Chinese.
One really famous poet from the 9th century was named Li Bai. He was from China and wrote lots of poems about nature and drinking wine. Can you imagine that? Writing poems about drinking wine! Another famous poet was named Al-Khalil ibn Ahmad. He was from Arabia and wrote lots of poems about love and beauty.
So, even though it was a really long time ago, people still loved to express themselves with poetry. And we can still read their poems today and appreciate the beautiful words they wrote.
