Wang the Second heard it, rolled straight out of bed, groped about in the pitch dark, and being a man in a panic, grabbed his trousers for a shirt: put his left arm in and it would not go, pulled it over on the right and that would not go either.
Two different jobs for one character in one line, and both are the same reading. 著 is zháo in both 著忙, which haste has taken hold of, and 撈著, to get hold of — the reading for something reached or landed on, not for an action held in progress. Then 當 is dàng, to take one thing for another. 一轂轆 imitates the sound of something rolling, and it is the verb for getting out of bed all in one movement.
The best sentence in the chapter so far, and it is about a man failing to put a shirt on. Everything is observed: rolling out, the dark, the panic, the wrong garment, and then the two attempts with the arms.
The novel is not laughing at him. The Great Sage Equal to Heaven is robbing him at midnight, and Wang the Second does the most human thing available, which is to get dressed badly. It is a small piece of realism dropped into a scene with a talking rat in it.
