Answer 2

You also asked whether 舒服 is a composite. In modern Chinese vocabulary, the unit of meaning is generally, but not always, two syllables. Two syllables corresponds to two characters, each of which generally can be associated with some set of meanings. To give you an analogy, when you hear the word 'breakfast' you think of one concept, right? You do not break it down into 'break' 'a fast', do you? Even more extreme, when you hear the word 'goodbye', you do not reflect on its meaning coming from "God be with ye", do you?
