Apart from the liturgy of the Daoists that is my main topic, many other concomitant mortuary observances tend to fall under the domain of “folklore”.
After a death in rural Yanggao, among all the complex arrangements shown in my film, there’s a tiny exchange (from 14.11) where the son of the deceased reads out Li Manshan’s prescription for the funeral arrangements.
According to the “old rules”, Slapping the Coffin follows the nocturnal Escorting Away the Orphan Souls ritual segment and the lengthy Crossing the Soul [aka Sitting Through the Night] instrumental sequence from the shawm band or Daoists (my book, p.128). Around half an hour after the band has fallen silent, when all is quiet, the oldest son and oldest daughter slap the coffin with their palms, crying out “Go, then” (Zouba, zouba 走吧，走吧). Then the son leads the way, sweeping the path while the daughter takes the paper cart (now often a car) from the funeral artefacts, kowtowing all the way to a crossroads, where the cart is burned.
By 2003 this procedure had commonly been simplified for some time, and even Sitting Through the Night was optional. But it’s an instance of all the minutiae formerly observed by the kin, beyond the more public rituals of the Daoist band—”customary” rather than “religious”.
The kin still observe elaborate, ancient distinctions in their funerary headgear—these are just the appendages for the female kin:
Left, sister; right, granddaughters.
But as ever, “customs differ every 10 li“. We should document both religious and customary rituals. Neither is timeless: we need to show how they change within local societies.
