在旧西藏,三大领主即官家(封建地方政府)、贵族和寺院上层僧侣约占全西藏总人口的百分之五左右。这些贵族的形成大体上可以分为以下四种类型: 第一类贵族称为“亚溪”。他们是历辈达赖喇嘛的家族成员,也是西藏最大贵族阶层。 第二类贵族称为“第本”。这些家族的祖先曾立过功劳或者是名门望族的后代,排大贵族行列。 In old Tibet, the three lords, the official (feudal local government), aristocrats and temple monks account for about 5% of the total Tibetan population. The formation of these aristocrats can generally be divided into the following four types: the first aristocrats called “Yaxi.” They are family members of the Dalai Lama and the largest aristocracy in Tibet. The second aristocracy is called “the first.” The ancestors of these families have made meritorious service or are well-known descendants, ranking the ranks of the aristocracy.
