Folk fortune tellers can figure out what your family members do and know everything. Is this a lie? How do they know?

It is true that some experts can understand life, but that is only a small part. Such people don't make a living by fortune telling. I don't know much about folk fortune telling, but some of them have some skills, so we can't generalize. Fortune-telling is dominated by the Book of Changes, and things change regularly. You can learn about the world from a leaf. At the moment when a person is born, the aura given to him by the stars in the universe determines his physical condition and personality at that moment, which determines his life, so life can only be improved irreversibly. The development of the material itself is reflected in the outside. If we know the inside from the outside, and people's spiritual qi and blood are manifested in the outside, we can infer his personal situation. Everything is regular, following the sixty-four hexagrams of the Book of Changes.
