Tianhuo (Heavenly Fire)
Traditionally, it was taboo to thatch roofs, repair stoves, or light fires.
Tianhuo (Heavenly Fire) is an inauspicious star in the traditional calendar. As the name suggests, it is related to fire disasters. Traditionally, on this day, it was forbidden to thatch roofs (which involves flammable materials), repair stoves, or engage in any fire-lighting or fire-starting activities to prevent fires. These taboos stem from a fear of fire, especially in communities with dense traditional wooden structures, where the consequences of a fire are severe, so extra caution was needed.
