One of the Twelve Spirits of Building and Elimination, meaning 'achievement and completeness.' Traditionally suitable for opening businesses, enrolling in studies, and marriage; unfavorable for litigation.
Cheng Day is one of the Twelve Spirits of Building and Elimination, emphasizing the meaning of achievement and completeness. In traditional date selection, this day is considered auspicious for tasks that require a successful outcome, such as opening a business, starting school, or holding a wedding ceremony, symbolizing a good start and smooth completion. Conversely, it was traditionally believed that litigation or lawsuits should be avoided on this day, as Cheng Day values harmony and completeness, which conflicts with the confrontational nature of disputes. Although these taboos are no longer strictly observed in modern times, some people still consult such traditional sayings when scheduling important inaugurations or ceremonies.
