The Neolithic Culture of Wuxi is an important part of Neolithic Culture in Taihu Basin which undergoes Majiabang Culture, Songze Culture and Liangzhu Culture in turn. At the beginning of 21st century , remains of house, cellars and tombs of Majiabang Culture was found at Pengzudun Site in Xishan district which could date back to 7000-6000 years ago. And during 700 years after the period of Majiabang Culture, Songze Culture was developed, starting the civilizing process of social complexity. About 5300 years ago, Liangzhu Culture was developed based on Songze Culture. There were many stone implements and pottery vessels of Songze Culture to the early Liangzhu Culture been excavated at Xianlidun Site by Liangxi River , while the biggest sacrificial relic of the end of Songze Culture was found in Chidun Site at the northern piedmont of Huishan Mountain. Taihu Basin in the period of Liangzhu Culture was an area with the most developed productivity and the most complicated social structure where huge sites, irrigation works and primitive writing had been discovered by archaeologists. This area is considered by the academia as a most persuasive holy land with largest scale proving five-thousand-year civilization of China. As development of productivity and increase of population, number of tribes in Taihu Plain increased strikingly and survivability of ancestors in Wuxi was further enhanced. Archaeologist discovered here top grade graves and tribes of middle-late period of Liangzhu Culture at Qiuchendun site in Xinwu district and Gaochengdun site in Jiangyin, which indicates that this area is one of the central settlements at that time. About 4200 years ago, for some unknown reasons, Liangzhu Culture declined rapidly.
