Why did Shen Kuo write a written talk about Meng Xi? Why did Shen Kuo write a talk about Meng Xi?

Shen Kuo lived in Meng Xi Park, without official documents and the courtesy of seeing him off. It was much colder, but it also gave him rare leisure time. Shen Kuo recalled his conversations with friends and his daily reading experience. When he thought of something interesting, he began to write it down, just like chatting with friends, in order to enjoy the loneliness after being dismissed from office.
