How does a fortune teller judge whether a person is a dog reincarnation? What are those?

This is a part of China's metaphysics, which cannot be verified. Personality and temper are all based on the combination of eight characters, and it doesn't matter what reincarnation. Since you can change from a dog to an adult, it shows that people have accumulated a lot of virtues before they can change from a dog to a person. There are many things to be changed in the middle, and the dog's temper must have changed, otherwise he is still a dog, so it is a bit deceptive to compare his personality and temper with dogs.
