제사 is a traditional Korean ritual that honors ancestors and deceased family members. It typically involves preparing a table with various foods, including rice, meat, and fruits, arranged in a specific manner. The ritual is performed on significant dates, such as anniversaries of death or during holidays like Chuseok. During 제사, family members gather to pay their respects, often bowing and offering prayers. This practice reflects the importance of filial piety and maintaining a connection with one's heritage. The ritual serves to strengthen family bonds and preserve cultural traditions in Korean society.
