From the Tibetan language "Xuhu" is transliterated to mean reliable friends, but the word is reserved to refer to friendship or harmony between the Tibetans and the Salar ethnic group in Salar Autonomous County of Xunhua, Qinghai Province. This bit of memory is part of the history of Qinghai. It is a reminder of the ethnic unity that grew between local Tibetans and Salar people.
