I think they' alive.You should konw some mortician\emblaming konwledges.Before massaging,the mortician will cut the veins in the neck to exchange the blood for the red liquid.To accelerate the process,morticians massages.The stick after massaging was to take in the poops inside the bodies.Both works should leave scars indispensibly.At least I can't find the scars.So they're just for a play,not for real
And the bodies look so good so fresh in skin.
But one thing I can't figure out.they don't breathe actually.And, their eyes are staring with no move~~~~I don't understand these 2 tricks.
