Ghosts are hungry ghosts and demons, and wizards can see them.

how to see the soul around you? Including the hungry ghost and devil you mentioned, all belong to this category, that is, to look at some living things invisible around you! The human eye is limited, and can only see light (called "visible light") with a wavelength of approximately 4nm (purple light) to 7nm (red light). If some living things are not in this band, we can't see them. That's the soul. Generally, there are only a few possibilities:

1. Instrumental measurement. Generally, it shows that the electromagnetic field is unstable. When Mr. Feng Shui measures Feng Shui, he will be very vigilant if the pointer moves.

2. Natural eyes can see. Commonly known as "yin and yang eyes" or "ghost eyes", you can see. There is also the "Eye of Heaven", which is more advanced than the eye of Yin and Yang. The eye of Yin and Yang can be seen directly, and the eye of Heaven is under the eyebrows, so you have to close your eyes before opening it.

3. The eye of heaven or the eye of yin and yang is temporarily opened. Sometimes it is urged by Master, so it can be temporarily opened for a while, and the length of time depends on the depth of Master's skill.

4, cultivate the eye of heaven. It's easy to see things around you.

5, perceptive. People with keen perception can find it by feeling.
