Blood from a black dog called Big Black, bought by Shi Meijiao for fifteen yuan (ten yuan for blood, five yuan for the basin). The dog was only about a month old. Shi Meijiao intended to pour it on An Ruoyan as part of a superstition ritual. An Ruoyan kicked the basin, causing the blood to spill on Shi Meijiao instead. The blood carried a risk of rabies.
