It appears that within the bottomless Ta-hoh or Great Canyon (see words 19 to 25) there is an illumination of torches (chuh) and a pulling up higher, or a dragging about and clinging to (yuen).
Climbing is here referred to. The Sun people seem to have found locomotion difficult and hazardous within the chasm.
