There is a folk song circulating in China: "Red eggs, full strings, eat your happy buns this year and eat your red eggs next year." Steamed buns are an auspicious wedding custom food. It is said that it is lucky for relatives to take it home to eat. Therefore, this ballad belongs to the auspicious language of blessing. Literally, the two red eggs at the beginning and end of this sentence have different meanings. The former "red egg" appears as a sacred object and has the function of praying for the blessing of the son. Then a "red egg" becomes a sign of the good news of a child's birth, and it is also an object that plays a role in announcing. Distributing eggs dyed red with pigments to relatives and friends is a popular way to express happiness all over the country. It is often used in wedding, childbirth, "full moon" and other festive occasions to show celebration and auspiciousness.
