Can a cow's tears touch her eyes and see something she shouldn't see?

If you put cow tears on your eyes, you can see things like ghosts, then some mysterious folk practitioners will use this method to prove ghosts, but I have been practicing for many years and have never heard of such a method. So don't listen to this rule.

Besides, as a person, you just need to be a good person. What are you doing, caring about those ghosts? The more you care about ghosts, the easier it is for them to find you. Confucius said "stay away from ghosts and gods" more than two thousand years ago. Therefore, keeping a psychological distance from ghosts and gods is the best policy.
