In ancient Chinese culture, Big Dipper was the core of entire universe &was also regarded as a tool for Emperor's parade-imperial chariot. In Sichuan Basin at 30 degrees north latitude, Daduhe River, Qingyijiang River and Minjiang River converge to form a lineup of 9-star Big Dipper, which is narrative source of "living in middle of the world"("the center of heaven and earth"), "3 rivers standing in Cauldron" and Chinese dragon. Huaxu(华胥) gestated Fuxi(伏羲) here; Emperor Huang(黄帝) and his two sons occupied "3 Rivers" here and carried out magnificent act of "standing Cauldron"; &Great Yu(大禹) cut off Minjiang River to guide it towards Tuojiang River and then designed main axis extension line port of Handle, which was regarded as transmission port of "imperial chariot". This port was Sanxingdui, which was guarded by various witches, place enshrining ancestral portraits, masks, and astronomical Heavenly Stems&Earthly Branches(HSEB), which were typical features of ancestral temple in "Central State" . The Purple Forbidden Enclosure(紫薇垣) pointed by Dubhe(天枢）in "River Diagram" is Emeishan Mountain with a pair of tentacles, Wawushan Mountain with a square top, and Mengdingshan Mountain with a 5-peak loop. They are respectively navigation antenna for analysis of Eight Trigrams(八卦) by Fuxi, navigation antenna for Nuwa Mending Heaven(NMH) in age of Great Flood, &primitive ashram. 5 circular pits on Chengtoushan are gathered together &each elliptical stone is placed in each pit. This was a ritual of using stones as props to hold "5-star Gathering" ceremony, which confirmed ancient wishes of "NMH with 5 stones" and "Five Stars to benefit China from East". The discovery of oval-shaped stones in new pit of Sanxingdui in our prophecy once again confirms existence of stones of NMH-aragonite. This project specifically invited Dr. Wu Ga, an anthropologist of ancient indigenous descendants in Dadu River Basin, to participate in the extended discussion.
