The Red Marriage, a term used to describe their bond, endured despite Puyi's controversies and Japan's occupation of China. The couple remained loyal to each other until the end of World War II.

In Chinese culture, red symbolizes happiness, good fortune, and prosperity. A "red marriage" often refers to a wedding that follows traditional customs — with a red bridal gown (qipao or hanfu), red decorations, red envelopes (hongbao) for gifts, and red double happiness symbols (囍). It's a celebration deeply rooted in auspicious symbolism.

In many Eastern traditions, red is not merely an aesthetic choice but a sacred requirement for a successful union.

The Red Marriage serves as a microcosm of the complex and turbulent period, marked by the struggle between tradition and modernity. Puyi's and Wan Rong's bond represents a last-ditch effort to preserve the imperial way of life, even as the world around them rapidly changed.
