I have never seen her before. When getting married in Taiyuan, the groom usually carries the bride upstairs as soon as she gets off the bus. Before entering the house, the bride's feet can't touch the ground, which is an ancient stress, or it may be to ward off evil spirits. Many weddings I attended were like this.

There are worse things now. After the wedding car came, it was stopped before it entered the community. The bride and groom were asked to get off and start carrying. A group of students are booing, and the entrance of the community is still far from home. Poor boy, rest on his back, and the people next to him have been joking: Do you want me to help you carry the bride? It's tragic. ......

As for what you said, I have never met it, and it is definitely not a custom in Taiyuan.
