(cf. *Secret History*, § 239; «Sanang Setsen» [Schmidt, 75, 155]; *Altan Tobči* [Gomboev, 133]; and
Grum-Grižmaĭlo, *Zapadnaya Mongoliya i Uryankhatskit krat*, III, 295). One might think of
the lineage of Badai and Kišlik (< Qišlïγ), the two Kerait shepherds whose advice saved Chinghiz-
khan when he waged war with Ong-khan and whose descendants had a particular privilege of drink;
this is the only sensible suggestion in the extraordinary jumble of wrong forms and misstatements
heaped up by Charignon (*Ch*, I, 224-225, 264-265). But «Horiat» (or «Boriat») is far from
*Carait (Kārāit, Kerait).

The name is Yači, written ياچى Yači in Rašīdu-'d-Dīn (*Bl*, II, 494), 押赤 Ya-ch'ih (*a*) (and,
with a wrong reading, 押赤 Hsia-ch'ih), 鴨赤 Ya-ch'ih (*b*) and 鴨池 Ya-ch'ih (*c*) in Chinese.
This town was certainly either the present Yün-nan-fu, or a town quite near to it and also on the
banks of the lake. But here the difficulties begin.

Yule was, as far as I can remember, the first to identify Yači with Yün-nan-fu, and this has
been accepted for many years; it implied that Yači was the same as 拓東 Chih-tung, founded in
764 or 765 by the Nan-chao prince Fêng-chia-i, renamed 鄯闡 Shan-shan in the 9th cent., and
according to Chinese tradition, identical with the present Yün-nan-fu. It seemed to be corrobo-
rated by Rašīdu-'d-Dīn, who, like Polo, says that Yači is the capital of the Qara-Jang province.
In 1904, Chavannes remarked (*TP*, 1904, 471-472; 1905, 4) that during his campaign in Yün-nan,
Uriyangqadai arrived first at Shan-shan, and later on took Yači, so that the two towns must be
different. Chavannes proposed then to leave Yači at Yün-nan-fu, and to place Chih-tung, *alias*
Shan-shan, at P'ing-ting-hsiang, in the northern part of the *chou* of K'un-yang. Although I was
then unable to offer any solution, I showed immediately (*BEFEO*, IV, 1098) that Chavannes's
hypothesis could not be accepted at its face value. Cordier, unaware of the problem raised by
Chavannes, said independently (*Y*³, III, 127) that the present Yün-nan-fu was built in 1382, and
that the Shan-shan of the Nan-chao kingdom lay to the south-east of it.

Only a provisional solution can be proposed, as the texts have not been thoroughly collected
and discussed. The only mention of Ya-ch'ih *b* which has been quoted from the *pên-chi* by Wang
Hui-tsu², 49, 4 *a-b*, is the one of *YS*, 8, 2 *b*, when, in 1273, a grant of money was made to Sayyid
Ajall who was sent to govern the barbarians (Man) of Qara-Jang, Yači (Ya-ch'ih *b*), Čitkör (wrongly
united by Wang Hui-tsu with the preceding name; see «Cogacin» and «Caragian»), Chin-ch'ih
(see «Çardandan») and Čayān-Jang; the only mention Wang Hui-tsu gives of Ya-ch'ih *a* is from
