What is the Cantonese equivalent for 你怎么样？ Colloquial Cantonese phrases often differ significantly from Mandarin, so I would be nervous to use 你怎么样 pronounced in Cantonese. 

Is there a greeting of identical (or nearly identical) meaning in Cantonese (ie, for closer acquaintances, implying "how are ya?" or "what's up?")?
Normally we use the verb &quot;点&quot;

你点啊？
Nei5 dim2 aa3?
leih dim a?
English: What's up? (less formal)
你点样啊？
Nei5 dim2 jeung5 aa3?
leih dim yeung a?
English: How are you doing? (more formal)
你近排点啊？
Nei5 gan6 paai4 dim2 aa3?
leih gan pai dim a?
English: How have you been doing?
你呢排点啊？
Nei5 ni1 paai4 dim2 aa3?
leih li pai dim a?
English: How've you been lately?
