During the "day," Han Mengyun focuses on painting, diverging from Eurocentric frameworks—both classical and contemporary—to delve into the complex historical ties within the profoundly intercultural context of Eurasia's past and present. Initially trained in the Western tradition of oil painting, she shifted towards embracing the complexities of historical ties and intercultural dialogues that have shaped the continent's history. The broad focus of her research covers interdisciplinary manifestations of cultural dialogue and polyvocal aesthetic conversations—from religion, philosophy, and mythologies to trade, vernacular craftsmanship, and bookmaking.

Her studies in Sanskrit, Persian, and Arabic, along with Indian and Islamic art and intellectual histories, have led her to forge an alternative paradigm for image-making. This paradigm is based on Indian and Islamicate miniature painting in manuscripts, inspired by the invention of paper and printing techniques in ancient China. She views the book as an open space connecting all cultures while maintaining the uniqueness of cultural perceptions. Therefore, her paintings are conceived as pages and books, paying tribute to the history of ancient globalization—such as the Silk Road—and the intercultural dialogues that have made the world inherently hybrid and interconnected.
