Renu's writing style in "Maila Aanchal" is characterized by its simplicity, lyricism, and vivid imagery. The author uses symbolism effectively, drawing on elements of nature, such as the river, forests, and animals, to represent the struggles and aspirations of the characters. The title "Maila Aanchal" itself refers to a region in rural India, but also serves as a metaphor for the marginalization and isolation of the characters.
