What is the translation and significance of a famous sentence in Li Sao?

"The road to Xiu Yuan is long, and I will go up and down" means that the road ahead is still long, but I will persevere and spare no effort to pursue and explore. I think the "repair" here should be interpreted as: (road) long. Judging from the text, "Xiu Yuan" should be a coordinate word, corresponding to "Qiu" in the next sentence.

Li Sao is Qu Yuan's masterpiece. Qu Yuan's illness, Chu Huaiwang's refusal to listen, flattery to cover up the Ming Dynasty, and intolerable evil songs that harmed the people led him to write Li Sao. Li Sao is a magnificent political lyric poem, which has a lofty position in the history of China literature. Written when Qu Yuan was exiled to the south of the Yangtze River, it was a poet's work full of patriotic passion to express his worries and indignation.

For the sake of ideals, Qu Yuan pursued tirelessly. He said, the road is long, and I will go up and down, which shows a spirit of persistent pursuit of truth.
