Candle for enlightenment which reminds us teaches.
Pig for enjoyment in its negative meaning, which is live for eating and dead by being eaten.
Enlightenment should with a light, so here it is, my uncle told me about a party secretary of a workshop, whose major enjoyment is to take a female worker to a secluded spot with high grasses for quite a long time, in the name of idea enlightenment...under a broad daylight.
Enjoyment may occur in dark or candle light as one can imagine, at night clubs, carnivals, those "er4 nai3" never work but enjoy luxury. These pigs list also include those plunderers...
Even a candle maybe is a little bit piggish compare with those burn by two ends. If one does not eager to be enlightened, although seems not piggish, but still can not take off this label.
