Is there an equivalent for the Cantonese phrase "M Goi" The Cantonese phrase "M Goi" has many meanings:


"Excuse me"
"Thanks" (casual)
"Hey"


Does it have a 普通话 equivalent? And how can I write it in pinyin? Is it even possible?
M Goi is written as 唔該 which in simplified is 唔该 or Wú gāi in pinyin.

The only thing I can think of that may be similar, although it definitely doesn't mean thanks is 劳驾 Láojià which you could use for "excuse me" or "hey" but not for thanks.
