Hui people practice a limited and open marriage system. Hui people regard marriage and family as the inevitable process of life ("Wazhibu", which means "of course"), oppose celibacy and support widow remarriage. Historically, the Hui nationality has experienced a transition from an open exogamy system to a limited open marriage with endogamy as the main factor and "foreign teachers marrying internally" as the supplement. During the Tang, Song and Yuan Dynasties, the ancestors of the Hui people mostly intermarried with "Han women". After the formation of the Hui people, intermarriage was the main form. Marrying foreigners is mostly in return for men marrying China women, and the other party must hold a conversion ceremony before entering the door. At present, on the one hand, the proportion of intermarriage among urban Hui youth is rising; On the other hand, the radius of Hui intermarriage in rural areas is shrinking. The Hui people practice monogamy. Before the founding of New China, the proportion of polygamy was also very low, which was related to the influence of Islamic culture. Hui people's wedding procedures include blind date (knowing each other's family, manners and appearance), engagement (engaging in morality and religion), receiving bride price (giving the woman a proper amount of bride price and clothes), fixing a date (agreeing on the wedding date) and holding a wedding. Among them, the wedding ceremony is the most grand, including wearing wedding clothes, welcoming the bride, picking up the bride, saying "Nikaha" (if married), sprinkling happy fruit, making trouble in the bridal chamber, playing with in-laws, recognizing the size, sewing, etc., which is very lively and unique. ?
