The things put in when filling the well need to be wrapped in red cloth or red paper. In the northeast, there is a custom when getting married, that is, before sunrise on the wedding day, wrap it in red paper or red paper, fill it in the well according to the chosen wedding route, and cover the manhole cover, which means suppressing bad luck and welcoming happiness. Although this is a superstition, as of August 24, 2023, getting married for good luck continues.
