A pig and a dragon match, which is a general marriage. Not the best, not the worst.
The so-called "big picture" of the eight-character horoscope is to look at whether the animal signs of men and women are in conflict with each other according to the zodiac. There is a local song "Big picture song":
Once the mouse and sheep rest, the white horse will make the green cow,
The tiger and snake will be twisted like a knife, and the dragon and rabbit will shed tears,
The golden rooster is afraid of the jade dog, and the monkey and pig will never end.
It is believed that only when the "big picture" is compatible with the horoscope can there be a basis for marriage. How to calculate the compatibility? There is a folk song that says:
The green rabbit and the yellow dog have existed since ancient times, and the red horse and the yellow sheep have a long life.
The black mouse and the yellow cattle are prosperous at both ends, and the dragon and the chicken match for a longer time.
It is rare to get married, and the family must be rich every year.
