(2) Khams or Khamdo, which includes all eastern Tibet between the Chinese, provinces of Szechuen and Yunnan, and the district of Lhorong jong, which forms the eastern border of the Lhasa-governed territory.
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."
The administrative subdivisions of the Lhasa country, of which there are fifty-four, are called jong, or " prefecture," each of which is under the rule of two jong-pon, the one a lama, the other a layman.
There are 123 sub-prefectures under jong-nyer.
They returned by much the same way to near Khamba jong, and re-entered Sikkim by the Donkya pass.
