Tianyi Marriage Matching is a traditional Chinese fortune-telling method used to predict the good or bad luck of marriage and the matching situation. Among them, the interpretation of the combination of Fu position and heavenly medicine in the numerical energy, such as 668, is as follows: 6 represents water, symbolizing feelings and emotional communication; 8 represents earth, symbolizing fixation and stability. Both are yang numbers, which means they support and complement each other. At the same time, the arrangement of 6 and 8 forms the homophony of "68", which means happy love and harmonious marriage. Among them, heavenly medicine represents auspicious health and longevity, and means happiness and contentment in marriage. Therefore, in the digital energy, the combination of Fu and Tianyi, 668, indicates auspicious marriages, happy relationships, stable relationships, and good development prospects.
