In the poem, Blake vaguely compares "tiger" to revolution; "Terrible symmetry" symbolizes the great power of the revolution; The "eyes" of the "tiger" symbolize the fire of the revolution; Tigerheart is the core of the revolution; "Terrible hands, terrible feet" is a symbol of revolutionary power; The tiger's brain is a symbol of the revolutionary guiding ideology. Explaining the "tiger" with vivid images is not only reasonable from the historical background, but also well-founded from the text. In the newspapers and poetry vocabulary of the British ruling class at that time, the French Revolution was "tiger and wolf". The Bible once compared the struggle against rape to "burning the forest". Blake has repeatedly compared the old system that needs to be destroyed to a "forest" elsewhere. He also said elsewhere that "angry tigers" are smarter than "teaching horses" in the hell world. The "angry tiger" here undoubtedly refers to those angry people; "Teaching horses" refers to priests who serve the ruling class. Therefore, it is well-founded to interpret "Tiger" as a symbol of revolution and "Lin Mang at night" as an old system that needs to be destroyed, whether literally or in a sense, from the historical background or from the poet's subjective desire.
