On the 14th day of the seventh month of the lunar calendar, the Gates of Hell burst open, and ghosts pour forth from the Nine Darknesses into the sunlit world. To placate the dead, Hell Money is burned, offerings are made, and paper boats and floating lanterns are set out to give comfort and direction to wayward spirits. Though many spirits simply seek out the comforts of their former homes and the company of their loved ones, rancorous spirits also roam the streets, seeking revenge on those who have wronged them, before and after their deaths. Offerings of joss paper, ginger candy, sugar cane, smoky vanilla and rice wine mingle with a ghost's perfume of white sandalwood, ho wood, ti, white grapefruit, crystalline musk and aloe. This scent is tapered by the presence of seven herbs, woods and resins used in the purification of the spirit and the purging of earthly concerns from the soul.
