There is blood at home for no reason. Try to find an answer or find out the method!

1. Find someone who has some research on forensic medicine to make a good investigation, and explain to you from a scientific point of view what's going on, whether it's blood, whether it's human, and the splashing situation, so that you can rest assured.

2. The blood spilled at different heights is different. If there is no trace of the crown on the edge, as shown in the figure, 10cm splashes at 90 degrees (vertically). In this case, there may be blood spattered on someone's hand (most likely a child), and the seriously injured blood spattered area is large, and it will take the shape of splash or other sputtering.

The so-called Taoist way, writing some unreasonable spells, is useless except psychological hints. This is self-deception. Those spells you wrote for An Zhen were to drive away all kinds of monsters that threatened the safety of the house and subdue the plague. These spells were commonly used in houses in the south.

If you have psychological obstacles, then move, but it is best to seek a scientific and objective explanation.
