In ancient China, "wild goose" was used as a bride price. Because geese are single-minded and only recognize one spouse. If one party dies, the other party will no longer choose a spouse. Therefore, the ancients used geese as a dowry to show their loyalty to marriage.

In addition, when men and women got married in ancient times, the man would stick a piece of "Hongluan Tianxi" in the house, and the woman would stick the word "Hongxi" in the house. The "Hong" here refers to the wild goose.
