The most common saying about what it means to receive a bride's bouquet is "to be the next lucky bride." The bride's bouquet of flowers is a symbol of happiness at the wedding, and for the person who grabs the bouquet, it is also a transmission and sharing of this happiness.
The flower bouquet stems from an ancient custom: Ancient Westerners believed that strong-smelling spices and herbs (even garlic and chives) could protect the wedding party from bad luck and disease, so the bride would carry a bouquet of fresh flowers at the wedding, hoping for a successful marriage in the future.
Later this custom was carried down and gradually took on more meaning. One of the most popular sayings is that an unmarried woman will find her happy partner when she catches the bouquet thrown by the bride at the wedding. Therefore, there are now many brides in the wedding bouquet will directly send the bouquet to their single girlfriends, in order to bless her about to encounter their beautiful love.
