Under the influence of the Tang Dynasty’s political system, etiquette system, social style and aesthetic style, official uniforms became common objects of writing in literary works.The official uniform was an external symbol of rank, identity, status and role awareness, and played an extremely important role in the political life of the literati.Among the literati of the Tang Dynasty, Bai Juyi’s official uniform writing is very representative, involving official clothing ornaments, clothing colors, and special official dress phenomena such as borrowing, giving, and pawning clothing, which constitute an important part of the Tang Dynasty’s ritual cultural system.The official uniform carries Bai Juyi’s complex officialdom experiences, role consciousness and mentality changes such as being enterprising and unwilling when he first entered his career, in a mixed mood when he moved to the top, and having aversion to officialdom and contentment when he retired in his later years, forming a multiple officialdom complex under the role of the cultural tradition of clothing, political domination and officialdom consciousness, embodying the role choices and struggles of the midTang literati under the complex political ecology, and opening up a new field for the diverse writing of midTang poetry in addition to enriching the content of poetry, adding poetic charm, and strengthening the poet’s emotions.
