What are the three fortune-telling halls?

Three halls refer to people's fortune telling, numerology and room changing.

1, fortune telling: by observing a person's appearance, facial features, bones and other characteristics, we can understand his personality, fate, good or bad luck.

2. Numerology fortune-telling: Also known as eight-character fortune-telling, it is to calculate this person's fate and fortune from heavenly stems and earthly branches's eight-character combination by looking at this person's date of birth.

3. House-changing fortune-telling: It is to infer the fate and fortune of people living in this house through the principle of geomantic omen and the orientation, structure and date of birth of the house.
