Mandarin Relative Clauses?

Hi!

I'm currently trying to understand Mandarin Chinese grammar.  I'd like
to know whether you think that the analysis of attributive adjectives
as relative clauses is justified?

What I want to say is that `hong putaojiu' (red wine) or `hao de
pengyou' (good friend(s)) is a construction like `he cha de ren' (tea
drinking persion, person who drinks tea).  I think this is an elegant
analysis, since adjectives are actually verbs in Mandarin and with
other verbs (like `to drink'+ obj), a pre-posed clause adjoined with
`de' is analysed as a relative clause.

Examples (I'll leave out a typical `very' (`hen') to make the
comparison nicer):

a) Na ge ren     he    cha.
   that  person  drink tea
       `that person drinks tea'.

   Na ge he    cha de    ren     shi pengyou.
   that  drink tea DE    person  COP friend
       `That person who drinks tea is a friend'

b) Na ge ren    mang.
   that  person (is)busy
       `That person is busy'

   Na ge mang de ren     shi pengyou
   that  busy DE person  COP friend
       `That busy person is a friend.'

I'd like to know whether who think the analysis as relative clause of
`he cha de' and `mang de' and others like `hao de' (good DE) in `hao
de pengyou' (good friend(s)) or `hong de' (red) in `hong putaojiu'
(red wine, the DE is eliminated) is justified.

I asked a person with mother tongue Mandarin about this.  Obviously,
the categorisation is less obvious as it seems, since `hao' (good)
seems to change its meaning if used attributively, preventing a clear
classification is a relative clause from the syntax only point.
