Travel far is a title in Song of the South. Wang Yi thinks that Qu Yuan did it, but modern scholars have many doubts about it. Some people think it was the Han people, but there is no conclusion yet. The title is taken from the first sentence of this poem, "custom forces me, I am sad, I would like to swim easily."

The lyric hero described in the poem deeply feels that the real world is desperate, oppressive and difficult to solve. Therefore, he envied going to the ancient immortals to be quiet and vain, and to get rid of the free and easy things, so he left the skeleton and decided to travel far without violating the old capital. Starting from his native land in the south, the hero first visits the heaven, "asks where the big and small live", and then travels around the quartet and octupole, finally reaching the ideal state of "no land to ignore and no news", detached from things and "first neighboring Thailand".

Poetry embodies the author's strong thought of transcending secularism and pursuing spiritual liberation. In art, the fantasy world is constructed by myths and fables, and the imagination is elegant, free and unrestrained, with magical and magnificent colors. Travel far has a great influence on the poems about immortals in later generations.
