What are the characteristics of Li Bai's later poems?

Li Bai's poems and songs sang his progressive thoughts with heroism, attacked powerful people and despised ethics. But there will always be negative emotions of incompetence and life like a dream. From the artistic point of view, his poems are rich in imagination, using bold exaggeration and simple language to form a bold and hearty style, and he is an outstanding representative of ancient positive romantic poetry after Qu Yuan. All the works in my life belong to romanticism.
