Dike Construction

Building dikes is a crucial engineering project to prevent floods and protect farmland and settlements. In the traditional calendar, selecting an auspicious day for 'Dike Construction' to begin work is meant to pray for a sturdy dike that can effectively resist floods, safeguarding lives and property. This type of auspicious and inauspicious day selection reflects the old agricultural society's reliance on water conservancy facilities and its reverence for natural disasters. While modern water conservancy engineering involves scientific planning, the related concepts of day selection are still recorded in traditional folk customs.
