At the long-distance bus station on the way to Anhui province, I met a Han journalist called Tashi. He had spent over a decade travelling through the Tibetan areas, and had researched and published many books on Chinese folk customs, and I took this chance meeting to benefit from his advice, talent and scholarship. Because we were both journalists, there was no need for too many preliminaries, we came straight to the point, and began with the topic that I had been hoping to discuss. * XINRAN: What sort of people are the Tibetan groups you've met in your travels? TASHI: I haven't seen Tibetans from every single clan, there are too many. Generally speaking, the area can be divided into three groups of people: the Amdo Tibetans, the Kangba Tibetans and the Huiba Tibetans. The Amdo people are mostly those on the high plains to the north of Tibet, around Amdo, Qula and Sangxiong, up towards the uninhabited areas. XINRAN: So what you're calling northern Tibet is to the north of the Tanggula Mountains?
