无论谈论那一个民族的历史,首先要以真实的族源或传承作为基础。藏族先辈学者也认识到它的重要而这样说过:“倘若人们不知道自己的血缘,就好比是森林里的猴子;假如不知道自己的世系,就好比是一条虚幻的青龙;如果不懂祖先的文书档案,就好比是四处漂泊的野人”。叙述一个民族的族源不同于叙述其民族的王统世系,是个深奥难测的问题。大家都以各自的观点,依据点滴资料来谈论。同样,对藏族族源问题,也以一些零碎资料为据,致出现好几种不同的观点。这些观点大部分掺杂着作者的一时需要和偏见,因而对解决藏族族源问题没有什么益处。我认为,这些带有偏见的观点应从藏族族源问题的讨论中除去。在此,我想将现在对藏族族源的三种说法及其来源向读者作一初步介绍并略加评说。 No matter talking about the history of that nation, we must first base on the real ethnic origin or inheritance. Tibetan scholars also recognize its importance and thus said: “If people do not know their own blood, is like a monkey in the forest; if you do not know your own lineage, is like an unreal dragon; if you do not know the ancestors Of the file, like savage wandering around. ” Describing the ethnic origin of a nation as distinct from the lineage of the reign of Wang Tong who described his people is a profound and unpredictable question. Everyone has their own point of view, based on a bit of information to talk about. In the same vein, there are several different opinions that have emerged on the issue of Tibetan ethnic origin and on some piecemeal sources. Much of these views are mixed with the author’s immediate needs and prejudices, and thus have no beneficial effect on the solution of the Tibetan ethnic origin. In my opinion, these biased opinions should be removed from the discussions on the ethnic origin of Tibetans. Here, I would like to make a brief introduction to the readers and give a brief comment on the three versions of the Tibetan ethnic origin and their sources.
