Last time I think throw to the sea too dnt need pple come to pray...
But some funeral owner share to us not good for dead pple
In the ancient days, one way to punish the worst criminal or enemy is to kill the person, hack the body into parts, burn and pound the bones into ashes and then throw them everywhere( 挫骨扬灰); so that the dead will
suffer in the afterlife eternally(永不超生).
That is why we should never ever scatter the ashes of your ancestors or loved ones everywhere whether it is on the ground or in the sea.
