Common themes include the connection between the living and the dead. In Chinese Ghost Bride stories, the living often interact with the ghost bride, which shows the thin line between the two realms. Another theme is the power of kindness. When the living show kindness to the ghost bride, it usually leads to a resolution. Also, there is the theme of fate. The ghost bride's fate was cut short in life, and her story in the afterlife is a continuation of that, often with the hope of breaking free from the chains of her tragic fate.
One common theme is unfulfilled love. The ghost bride often died before her wedding day, so her love was left unfulfilled, and she haunts the living world in search of closure. Another theme is the idea of redemption. For example, when someone helps the ghost bride find peace, it's like a form of redemption for her sad fate. Also, there is often a cultural aspect, like the importance of traditional wedding rituals, which might be used to solve the problem of the ghost bride's haunting.
