What is a wife and a palace match?

"Matching wives and palaces" is a folk fortune-telling statement about men's and women's marriage, indicating that fate is suitable.

For example, white horses have been afraid of green cattle since ancient times.

Sheep and mice meet once, but rest.

The marriage between snake and tiger is like a knife,

Rabbits exchange tears when they see the dragon king.

The golden rooster and the jade dog can't escape,

Pigs and apes will not end.

There is no scientific basis.
