Pilgrim led his master, Sha Monk took up the load, and they went along behind the lantern's shadow straight to the chest.
The same manoeuvre as the staircase, and for the same reason. 擔 is dàn, the noun — the shoulder-pole load — and 著 is zhe, the leading held in progress.
Bajie, not caring which way was up, scrambled into the chest first.
The verb here is one of the two rarest characters in the chapter, and it belongs to spoken Ming rather than to the written language. Its shape combines the foot radical with a phonetic that gives it the sound guā, and across the novel it always takes a direction after it — into, out of, up onto. The sense is to scramble or clamber, to move by the legs in a hurry and without dignity, which is precisely Bajie getting into a box. The old rime books gloss the character as a noun meaning the creases of the foot, and that is not what the novel means by it.
Bajie goes in first without being asked, which is characteristic, and the novel picks a verb for it that nobody would use of a dignified person.
不管好歹 is not minding good from bad, not stopping to work out which is which. It is the same pairing of characters that described Pilgrim's fiery eyes early in the chapter, where he could tell good from bad at a glance. Bajie cannot and does not try.
