What's the effect after the well is filled?

It doesn't matter. This is superstition. The following is the legend:

1. There is a certain ceremony for well filling. It should not be buried at will, let alone built on the well. There will be supernatural phenomena, unsafe houses, and many diseases in your family.

2. Choose an auspicious day: usually choose "closed day" (some teachers advocate that "God's forgiveness day" can also be chosen to prevent crime).
