How to fill an old well? There is an unused well in my house. How to query the date of well filling?

You can choose a suitable day on the yellow calendar, or you can find daily taboos on the calendar. When the date is chosen, you can prepare some paper money and six packs of yeast in advance, burn the paper money into the well and add it back, and then start adding soil. When the remaining 60 cm is added, put six packs of yeast around the edge, then lay it flat and compact it.
