Sealing Caves
Sealing holes and crevices, traditionally to prevent insects and rodents.
Refers to filling holes and gaps in walls, floors, or buildings. Historically, the primary purpose was to prevent insects, rodents, snakes, etc., from entering indoors, ensuring residential safety and hygiene. As it involves repairing building structures, it has traditionally been considered a minor earth-moving activity that requires choosing an auspicious day.
