To bobo,
your answer is very clear and interesting. is there a reference for me to read more? thank you!

兩樣都唔係。首先，「luxury in life」中並不存在動詞，所以唔會係phrasal verb。其次，只有經常出現的慣性組合（例如：not at all, resounding success, crying shame, etc）我們才會稱為collocation，而「luxury in life」卻不是。若想將「luxury in life」歸類，可對它作出分析。「luxury in life」的組合是noun + perpositional phrase，所以應當為noun phrase.
