According to bshad mdzod chen mo, Mu has eight sub-clans: ngam, snubs, gzhung, 'gar or mgar, dkar, smon, snyos or gnyos, ngan lam. According to The Treasure of the Ancestral Clans of Tibet, based on the Golok Rudzod, the Mu clan is also known by different names, such as dmu tsha sga, thang le sga, rmu, dmu and sga. They were said to hold the three vast plains of Kham Yarmotang, the Jang Karmotang and Tsongkha Lakyitang of Amdo. The Ga includes nine separate sub-clans: including Adro/ sga a gro, Arik/ sga arik, Adruk/ sga a ‘brug, Atrom/a khrom and Ashing/ sga shing, established by the nine separate children of dmu tsha sga.
