Night weddings are very common in many southern provinces, and most of them have been night weddings in northern provinces such as Tianjin. There is even a saying in Tianjin that a wedding during the day is a second marriage. According to the historical data "Biography of White Tiger", "Married people are called salutes at dusk, so they are married". In other words, holding a wedding at night is a long-standing wedding custom of the Chinese nation. Shi Kangning further introduced that in ancient times, there was always a saying that "the bride was married in the morning and the bride was married at night". In ancient China, the bride's sedan chair was held after dusk. The homonym of "Marry and Faint" in Marry and Dusk is also an example of ancient people's night marriage, which shows that women change their surnames after getting married at dusk. Beijingers used to get married during the day after the Qing Dynasty. For political reasons, the "curfew" imposed by the Qing Dynasty forced young people to change their weddings to daytime.
