Tea buried in the Han Yangling mausoleum

node

Plant remains recovered from the tomb complex of Emperor Jing of Han near Xi'an were identified as tea leaf buds through phytolith and biomolecular analysis, giving the earliest secure physical evidence of tea anywhere. Comparable remains from the Gurgyam cemetery in Ngari, western Tibet, dated to around the second to third century CE, show tea already moving across the Tibetan Plateau. Together they push documented tea consumption and long-distance tea movement several centuries earlier than textual records alone allowed.

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