I will sit on a fishing rod and listen to the quotation from the stream lazily. What is this allusion?

It is said that Lu Shang (Jiang Taigong) met Zhou Wenwang while fishing in Panxi (now southeast of Baoji City, Shaanxi Province). It is said that on the eve of being hired by Shang Tang, Yi Yin dreamed of passing by the sun and the moon by boat. Both Lu Shang and Yi Yin helped the emperor to establish immortal achievements, which showed that Li Bai still had great hopes for his political future.

Borrowing the allusions of Bixi, a place where Lu merchants fished, and Dream Boat in Yi Yin, he dreamed that one day he could trust and reuse the rulers like the ancients and build a great cause. When his thoughts came back to reality again, he still felt the hardships of life. Looking forward to the future, he only feels that the road ahead is rugged and there are many detours. Where is the road?
