In Henning Mankell's novel "The Man from Beijing," the metaphor of cold as handcuffs suggests a sense of confinement and oppression. This imagery evokes feelings of restriction and helplessness experienced by the characters, straining under various circumstances. The cold represents not only physical chill but also emotional and social bleakness, reflecting the struggles faced by individuals within the narrative.

Conversely, the heat symbolizes freedom and release. It serves as a transformative force that can unlock the shackles imposed by cold, representing hope and the potential for change. The idea that warmth can liberate implies a journey toward overcoming adversity and achieving a sense of autonomy and empowerment, motivating the characters to seek a brighter future amidst challenges.
