It is a representative work of the Chimu culture, an artifact from 1200 to 1440 BC, originating from Peru. It consists of two oval parts with a flat bottom, one of which is turned upside down to form an opening, and the other is decorated with the image of a bird's head. The unique design not only shows the exquisite ceramic art technology in Chimu culture, but also reflects the aesthetic taste and cultural characteristics of the society at that time. It is of great value in cultural and historical research, not only showing the artistic characteristics of Chimu culture, but also reflecting the lifestyle and religious beliefs of the society at that time. It was an important civilization in the Andean region of pre-Columbian South America.
