These two sentences reflect the poet's lack of talent, unable to stretch his ambition, unsatisfactory official career and depressed mood. He wants to get away from this sad environment, get rid of his troubles and go to a happy new world-life is so unsatisfactory, it is better to spread his hair and sail to sea tomorrow! The poet felt that his ambition could not be realized, so he had to take the road of long hair, travel around the world without cooperation with powerful people and be free. This attitude of "sending a boat" is not a passive retreat, but a resistance with positive resistance factors. Broad-minded, bold and natural language.
