Okay, so a long, long time ago in China, there was a group of really, really smart people who were very good at writing books and stories. These people were called literary eminences.
During a time called the early Tang period, there were four especially famous literary eminences.
The first one was called Wang Bo. He was a really good poet and wrote about things like nature and love. He was also really good at playing music!
The second one was called Yang Jiong. He was really into history and wrote about important things that happened in the past. He also wrote about nature and animals.
The third one was called Lu Zhaolin. He wrote a lot of stories and was really good at making people laugh. He would often write about funny things that happened to him or his friends.
The last one was called Luo Binwang. He was really good at writing poems that made people feel emotions. He would write about things like sadness and longing.
All of these people were really important and their writing is still remembered today, many, many years later.
