卻似經緯 Warp And Weft Of Silk
好大聖，束一束虎皮裙，掣出金箍棒，拽開腳，兩三步跑到前邊，看見那絲繩纏了有千百層厚，穿穿道道，卻似經緯之勢。用手按了一按，有些粘軟沾人。行者更不知是甚麼東西。好大圣，束一束虎皮裙，掣出金箍棒，拽开脚，两三步跑到前边，看见那丝绳缠了有千百层厚，穿穿道道，却似经纬之势。用手按了一按，有些粘软沾人。行者更不知是甚么东西。
逐句解 Line by line
That fine Great Sage tightened his tiger-skin kilt, drew out his gold-banded cudgel, stretched his stride and in two or three paces was up at the front of the place. He saw that the silk cords were wound a thousand layers thick and more, threaded through and crossed over, for all the world like warp and weft on a loom.
拽 is yè — the fifth of the chapter's seven, and the second of the four that stretch a stride rather than trail a skirt. 經緯 is warp and weft, the two directions of thread on a loom; the same two characters give modern Chinese its words for longitude and latitude. 穿穿道道 doubles both halves for the criss-crossing.
He pressed it with his hand and gave it a push: it was sticky and soft and clung to the skin.
粘軟沾人 — four characters, and each one is a physical property. Sticky, soft, catching at whatever touches it. This is the first thing in the chapter that anybody actually tests.
Pilgrim had no idea at all what the stuff was.
更 is gèng, an intensifier — still less, not at all. It is worth stopping on: the character who sees through every disguise in this book is looking straight at the thing and cannot name it. Ten characters to say so.
Pilgrim arrives and the first thing he does is touch it. Everybody else in this chapter has looked at things and drawn conclusions; he presses the web with his hand and finds out that it is sticky.
The loom image is exact rather than decorative. Warp and weft are the two thread directions in weaving, and the point is that the web has structure — it is not a tangle, it is a fabric, made by something that knew what it was doing.
And then the admission. He does not know what it is. This is the character who sees through disguises as a matter of routine, standing in front of the obstacle with no idea, and the chapter says so in ten characters without making anything of it.
