Minghun, i.e. afterlife marriage

The rural folk custom, startling to Western sensibilities, is known as minghun, or afterlife marriage. Scholars who have studied it say it is rooted in the Chinese form of ancestor worship, which holds that people continue to exist after death and that the living are obligated to tend to their wants — or risk the consequences. Traditional Chinese beliefs also hold that an unmarried life is incomplete, which is why some parents worry that an unmarried dead son may be an unhappy one.
