There is a folk saying that "pigs come to poor dogs to rich cats to open pawn shops".

As the saying goes, "pigs come to be poor, dogs come to be rich, and cats come to open pawn shops", which literally means that pigs become poor when they come, because pigs are lazy, dogs become rich, dogs are hardworking and simple, and cats can make money when they open pawn shops. This is a symbol of good luck. These statements do not have much scientific basis, mainly based on their characteristics.

Pigs always give people the impression that they are lazy and stupid. For example, calling someone a pig is an insult to others, so pigs are not popular in meaning, so there is a saying that "pigs come to poverty." People think that if a strange pig enters their house, it means bad luck and the family will become poor and decline.

Dogs in rural areas are different, especially garden dogs in China are very common in rural areas. Dogs are very spiritual, know how to communicate with people, are very hardworking and loyal, and will be very good to their owners. Even if farmers go out to work at ordinary times, they will follow, and they will help to look after the house at night and follow their masters without regrets. Moreover, dogs like a harmonious family atmosphere very much. If a strange dog suddenly comes to their house, it also shows that their family is harmonious and has a good family atmosphere. Such families tend to live relatively well and their careers are relatively smooth, so there is the origin of the proverb "dogs come to make a fortune".
