2. The whole poem of "Regret for the Remains of My Life" is: You should know that when you were young, Ling Yunzhi once promised to be the first class in the world. I don't know how many years have passed, but I still have neither fame nor fortune. Don't forget your great ambition when you are young, but make up your mind to be a first-class figure in the world. I didn't know that time passed quickly and quietly, and I still didn't gain fame and interests as before.
3. Appreciation: This poem reflects the poet's persistent pursuit of the ideal he advocates and his firm and enterprising spirit of mission. At the same time, it shows the poet's selfless spirit, strong and brave quality, and his sense of hardship for the nation and his own life. Poets often lament that they have an empty heart to serve their country, but they can't be reused, so they are extremely sad and write this poem to release their feelings.
