It has been discussed that Pyeonggeo-dong site has the Northeastern factor but the characteristics of potteries are closed to the c factor, and the native ‘Pyeonggeodong double-rimmed pottery’ were dominated. However, some potteries of BAL styled pottery as well as pot styled pottery that were characterized by its rim of pottery, made of the same techniques, were found. There are BAL styled pottery and pot styled potteries that were not made with folded rim of pottery and attached clay ribbon. In addition to these potteries, not- doble rimmed pot typed pottery, little pottery, beak styled stoneware, chipped stone hole, polished stone knife, oval pestle, disk styled stoneware, etc. are the main factors found in Sinigai culture of Maritime Province. I believe that the reason why Pyeonggeo-dong is considered as the filiation of the Sinigai culture of Maritime Province is because that Sinigai culture has been not well known. Therefore, I want to review that culture in this paper. Sinigai culture has been studied only for its regional boundary and characteristics. However, it is needed to review the chronological change of the potteries and start period of the culture and then compare to Pyeonggeo-dong site. Sinigai culture can be divided in to two types in each region, the West and East, based on chronological order and artifacts. The West 1 type had lasted from 3,400 to 3,200 years ago when people still used Neolithic potteries and started to make MOOMOON pottery. DOLDAEMOON pottery with pattern neolithic, one handle pottery, big pottery, polished stone dagger, polished stone ax, stoneware shaped star, disk styled stoneware, chipped stone hole, etc. were used at the same timew. The West 2 type lasted from 3,200 to 2,500 years ago. This is dwelling pit of square-shaped fire pot with stone and foundation in HARIN site. DOLDAEMOON pottery with pattern neolithic, pot withwith pattern neolithic on the surface, one handle pottery, BAL styled pottery, pot styled pottery, bottle styled pottery etc. are MOOMOON pottery. There are difference in their types based on the length of rim and neck in pot styled pottery and bottle styled pottery. In terms of the stone tools, there are oval pestle, stoneware shaped arrow, polished stone spear, polished stone knife, disk styled stoneware, chipped stone hole, etc. The East 1 type had lasted from 3,300 to 3,000 years ago. The symbolic potteries of this type are pot styled pottery with folded rim of pottery, BAL styled pottery with attached clay ribbon Knapped stone tools had been continuously used while the ground axe were appeared. The East 2 type lasted from 3,000 to 2,500 years ago. When it comes to dwelling pits, there are 3 rectangular fire pit, with foundation, and 4 lined pillar holes on the ground. notdoble rimmed pot styled pottery and bottle styled pottery are also found. People used various ground stone tools including stone axe, stoneware shaped arrow, stone arrow, polished stone spear, polished stone knife and etc. in addition to the knapped tools. BAL and pot styled pottery of doble rimm wth clay ribon, pot typed pottery with folded rim, and smaller potteries are related to the East 1 type of Sinigai culture. not-doble rimmed pot styled pottery rectangular mano, polished stone knife, chipped stone hole, etc are the factor of the West 2 type of Sinigai culture. Therefore, is can be considered that the material culture of Pyeongggeo-dong is combined with the East 1 type and the West 2 type of Sinigai culture. It is assumed that the Sinigai culture came to the west Gyeongnam Provinec continuouly from about 3,300 years ago until the second type that includes bronze artifacts. On the other hand, Daepyeong site located alongside of the Nam river has Gokok bronze which can be the earlier than Korea Liaoning bronze dagger. It is possible that the Gokok bronze was also a remain of Sinigai culture.
