How should that crowd of demons know true from false? They saw a man and lifted him, and put the false Pilgrim into the third tray up;
The narrator asks the question on the demons' behalf and answers it in the same breath. 見人就擡, saw a man and lifted him, is four characters of workplace indifference.
and then they yanked the Tang Monk over, bound him upside down, and lifted him into the fourth tray.
