The significance of the bride's marriage is that, in the traditional saying, the bride looking back will leave bad luck to her family, which is very unlucky. In the former farming society, the idea of male superiority and female inferiority was serious, and the bride did not look back when she married was a symbol of the husband's family requiring her wife to focus on the husband's family.
In modern society, there is no special meaning for the bride to get married, and the bride turns back to express her reluctance to her parents, and there is no bad meaning.
