During the "night," Han Mengyun explores her personal, emotional, and psychological experiences as a woman and a mother. Her affinity for the night developed from an uncontrollable desire to write poems in darkness during episodes of postpartum depression. The night emancipated her and inspired her écriture féminine. Her feminist awareness and radical solidarity were kindled by Gayatri Spivak's critical concern for the subaltern, the contradictions of existence as double binds caused by colonialism and modernity, and creative play as non-compliance. The subjects of intersectionality and legacies of imperialism are significant recurring tropes in her practice.

She mediates the relationship between the personal and the collective from her experience as a female subaltern, exploring emerging notions of alternative solidarity in the struggle for visibility and just access to shaping planetary cultural discourse. From writing and filmmaking to painting and textile installation—often merging these forms—her Night Practice examines women's experiences, utterances, and art forms in transgenerational, transcultural, transhistorical, and inter-religious contexts, probing the roots of subalternity and the possibilities of liberation.
