2. Interpretation: The road ahead for the pursuit of truth is far and long, and I will spare no effort to explore up and down.
3. From the 97th sentence of Qu Yuan's Li Sao. Expressed Qu Yuan's indomitable positive attitude. Qu Yuan's cry when he was demoted to Chu showed his patriotic spirit of not giving up his political ideal and hoping to return to the motherland, leading the country to the right path and resisting aggression. Xiu Yuan is a long road, and I will go up and down to seek for it. It shows the poet's life struggle for lofty ideals, strongly expresses his anguish and ambivalence when he was killed, shows his spirit of dedication to the country, and shows his deep patriotism and sympathy for the people who share the same fate with the country, and shows the poet's indomitable spirit of pursuing truth and light and upholding justice and ideals.
