For convenience of classification we may include in Khamdo a long strip of country extending along the northern border of the Lhasa territory of Lhorong jong and Larego as far as Tengri Nor, and bounded to the north by the Dang-la mountains, which is designated by Tibetans as Gyade or " the Chinese province."
From this point it leads to Riwoche, and then through Gyade or Chinese province to Nagchuka and Lhasa.
Here the party was stopped by Tibetan authorities and forced to take the tea route through Chinese Tibet (Gyade) by way of Batasumdo, Chebotenchin, Riwoche, Chiamdo to Chiangka, near the upper Yangtse-kiang, whence they proceeded to Tachienlu by Batang and Litang.
At this point Bower was stopped by some of the headmen of the Tibetan pastoral tribes (here under the rule of Lhasa), and obliged to make a long circuit to the north well out of Lhasa territory, and then eastward - till he struck the road to Chiamdo through Gyade or Chinese Tibet.
Here they were finally stopped by the Tibetans, and after a delay of six weeks passed in vain attempts to obtain permission to go to Lhasa, they were only allowed to proceed to Nagchuka on the Sining-Lhasa road, and to continue by the Gyade route to Yekundo, near the upper Dre chu, and thence to Sining in Kansuh.
From Nagchuka the travellers followed a heretofore unexplored road through the Gyade country, crossing Rockhill's route in the Pere-Sangyi districts near Tashiling (their Tachi gomba).
