Abstract: The main cultural remains of the Sanxingdui site are divided into four major periods, but there is an obvious missing link between the cultural remains of Sanxingdui Period I and Period II. Since 1999, through new excavations and the sorting of materials from previous excavations, a new group of cultural remains has been found in several locations of the Sanxingdui site, with a cultural appearance between Sanxingdui Period I and Period II, and almost identical to the pottery group of the Period III cultural remains of the Yufu Village site in Wenjiang. This has filled the gap between the first and second periods of Sanxingdui, and basically solved the inherent relationship between the late Neolithic and Bronze Age pottery groups at the Sanxingdui site. In addition, besides the site of Sanxingdui and the site of Yufu Village, there are another 33 sites (locations) in the Chengdu Plain where this group of cultural remains has been found, and similar findings have been made at the Sujiaba site in Wusheng County in the eastern part of Sichuan Basin. Although Group A pottery in this group is common in the late stage of “Sanxingdui I - Baodun culture”, the newly emerged Group B pottery already belongs to the category of “Sanxingdui Culture”, so it is obviously inappropriate to classify this group into “Sanxingdui I - Baodun Culture”, and at the same time, in view of the high proportion of Group A pottery and the fact that Group B pottery has not yet occupied a dominant position, it seems inappropriate to include it into “Sanxingdui Culture”, considering that the archaeological cultural remains represented by this group were widely distributed in the Chengdu plain, so it is appropriate and necessary to single it out and name it as a new archaeological culture.
