BC at Tsupaiku Langshisa Glacier on "T" in Glacier name on map
C1 at rock ridge on left side of South Face
C2 at small glacier right side of rock ridge
High point at a small summit south-southwest of Langshisa Ri's summit
on west edge of South Face.

First attempted via rock slope to C1-site on rock ridge and to C2 across ridge to small glacier and on flat glacier which is South Face to point (also 5800m) where could see above on South Face many very wide snow avalanches coming down from summit. So abandoned this route on 17 Oct and same day tried another route by crossing this small glacier (which faces South Face) further to east but stopped by hanging glacier at about 6000m and retreated to BC via night stop in C2 to sleep. 20th 3rd route making from C2 up ridge (rock at lower part snow at upper part) to point 6175m. Difficult rock and snow knife-edge ridge and sleep in C2 on night of 20th and again on 21st after having reached summit of point 6175m. 22nd down to BC and climb finished. Had abandoned hope of reaching main summit when abandoned 2nd route. All 5 climbing members and Ang Gyalu Lama to top of point 6175m.
