I am fond of the simile structure "I eat like a wolf" or "The light flickered like a candle" in English. I never know how to express these thoughts in Chinese though, even if I know the underlying words. How do I express this style of simile in Chinese?
This is indeed a complex matter. From the way you ask, I guess you're interested in the grammatical aspect, which is what this answer is focusing on.
Because Chinese language uses serial verb construction, the simile is expressed as a V-O (verb-object) clause with simile connective as verb and vehicle noun phrase as object.
