Abstract: It began with the Maogusi(毛古斯)ceremonial dance of Tu gia, treated of the relationship between primitive regions and primitive dance, and the specific form of the phallism in primitive dance.By considering the background of drawing the dancing incised line on the Da tong(大通)painted pottery, the dance on the Da tong(大通)painted pottery was regarded as a type of dance for phallism.The dance which was played arm in arm and step for step was the main type of the primitive dance, it was also the origin of today's song and dance.Maogusi(毛古斯) and Da tong(大通) dance were also the manifestation of the religious worship of phallism.
