良渚文化
It is believed that Liangzhu culture was the ancestral homeland of Proto-Austronesian populations before they spread to Taiwan, and Southeast Asia. Over time, the southward spread of Han Chinese led to the sinicization of most of the Baiyue populations that remained in Southern China, whether in the Yangtze Valley or in coastal areas from the mouth of the Yangtze to the Gulf of Tonkin. The remnants of these peoples who were not fully sinicized are now recognized officially as the ethnic minorities of the People's Republic of China.
