Looking at the sea, Cao Cao climbed the mountain to see what the sea saw-depicting the rivers and mountains of the motherland and drawing mountains in an instant.

This four-character poem depicts the magnificence of the motherland's rivers and mountains by climbing mountains to see the sea. It not only depicts the moving image of mountains and seas, but also expresses the heroic and optimistic enterprising spirit of the poet. It is a masterpiece describing natural scenery in Jian 'an period and one of the earliest representative works of China's classical landscape poems.
