Here, Li Bai compares himself to Wang Chen Cao Zhi. In addition to what LZ said, it can be mentioned that Cao Zhi was suspected by Pirui, and his ambition was difficult to show, which aroused the poet's sympathy and was similar to the poet's own experience. Therefore, the whole poem seems to be indifferent to politics from the beginning, but it actually implies a profound sadness and resentment. At the same time, because he compared himself to Wang Chen rather than other unknown drinkers, it can be seen that the poet is extremely confident, so there is sorrow without injury, and there is sorrow in sorrow.
