Laurent Sagart discusses how
Tibeto-Burman's and Austronesian's language families were genetic and came from the same neolithic patterns of Cishan, Peiligang, and Jiahu complex which overlapped with Yangshao. They farmed millet as their sacral crop. Dapenkeng on Taiwan, noted for its similarities to Yangshao also farmed millet, also treated as a sacral crop, not rice.
Neither Hemudu nor Liangzhu had millet.
There are still remaining, though quite few, remant matriarchs still upholding the culture of the ancient neolithic millet farmers originating in the upper Yellow River. Most of them don't practice the culture any longer as the global village continues to grow and matriarchy is no longer taught to the next generation.
