Since the discovery of the mermaid basin, the meaning of the mermaid pattern has aroused heated debate in academic circles. There are several widely accepted views: First, it is believed that the mermaid pattern is the product of totem worship at that time. Second, the "wizard" who prays for exorcism should wear a mask to show holiness, solemnity and mystery. The fish pattern on the face is a special pattern when the wizard presides over the sacrificial activities. Third, the population growth rate was very low at that time, and people hoped to reproduce like fish. Although today's people can't know the true meaning of the fish face pattern on it, this pattern with rich cultural connotation still gives people a strong impression and beautiful feeling today.
