Use Kumantong or Taoist Talisman is more straight forward. Just shake a cup or use pendulum. No need to waste time to study the numbers from the 4D Prediction Software.
Unless You really love to study Numbers , You shall 1st get the 4D Numbers from Kumantong/ Ghosts etc or from Taoist Talisman ,then re-fine-tune to improve the 4D Numbers.
