Bo Han is a symbolic poet with the most rebellious spirit. After Baudelaire, he and Malamei were called the three great symbolist poets. Bo Han developed Baudelaire's correspondence theory and the suggestive function of poetry. He believes that poets should be "psychics" and their task is to explore the mysterious "unknown" through emotional dislocation. His poems "Vowel" and "The Alchemy of Literature" vividly developed Baudelaire's synaesthesia theory, while his masterpieces "Drunk Boat" and "Dawn" are famous for their magnificent imagination and ingenious synaesthesia. For a time, symbolism poetry prevailed in France and influenced Europe and even the whole world: Bo Han, a psychic, invented "alchemy of words" and created "new flowers, new stars, new meat and new language".
Bo Han brought surrealism to French symbolism literature. Symbolists strive to discover (or decipher) the truth hidden behind everyday things, while surrealists further demand that the truth beyond things be created through intuition and fantasy. In this sense, Bo Han is one of the more radical French symbolist poets.
Bo Han's poems are famous for their gorgeous colors. 187 1 September, the young Bo Han came to Paris at the invitation of Wei Erlun, and soon became famous for his poem The Drunk Boat. In this poem, the poet compares himself to a drunken boat without rudder and anchor, drifting freely. The poetic style is complex and gorgeous, and it is a masterpiece in symbolic poetry. In another famous poem "Vowel", Han Bo used five different colors to symbolize five vowels in French, and then through specific description, he interwoven factors such as shape, color, taste, audio-visual and movement to achieve the realm of synaesthesia. In addition, the prose poem A Season in Hell is also a rare work of genius.
Although Bo Han and Wei Erlun are very close and had a homosexual relationship with Wei Erlun, their styles are quite different. Wei Erlun is good at natural and harmonious sounds, while Bo Han is famous for his peculiar images and fantastic colors. In 19 12, Rambo is regarded as the originator of the emerging surrealist literature.
