When an ancient bride got married, she covered her head with a piece of red silk, which was called a red hijab. There are many sayings about this custom, some say it is to hide shame, some say it is to bless the bride to enter the bridal chamber safely, and some say it is to keep a sense of mystery. The red hijab can only be taken off in the bridal chamber at night, and it must be taken off by the groom himself.
Ancient brides covered their heads for a long time, sometimes even more than a day. The ancient hijab was much thicker than it is now, and it was opaque and airtight. This may make brides feel bored and flustered, but there is nothing they can do, because it is a traditional custom, and it will be considered unlucky not to follow it.
