Serindia 162 - Last ruined farm of Kuan-tsou, north of Nan-hu - Stein stopped only briefly at the Han wall when he found it on his way to Tun-huang - Then after viewing the 'cave of the 1000 Buddhas' and realizing he would need quite a while to obtain some of the contents, he went to nearby Nan-hu and then back north to look for the western end of the Han wall - on the way he found this and the other ruined farms deserted after the Tungan rebellion.
