A dated phylogeny puts Sino-Tibetan at roughly seven thousand years

node

Sagart and colleagues published a dated phylogeny of Sino-Tibetan based on a curated cognate dataset, obtaining a root age of the order of seven thousand years before present and associating the family's origin with early millet agriculture in northern China. The date is materially older than that reported by a second phylogenetic study of the same family published in the same year.

A node is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
