What should I use to say "I love you": "wa ai lo" or "wo ai ni"? Some of my Chinese friends speak Chinese. I asked them how to say "I love you" in their language, but most of them said "wa ai lo" not "wo ai ni", how can this be?

I look for google translate, it says "wo ai ni" and not "wa ai lo".

Am I missing something here?
Here's a list of how to say &quot;I love you&quot; in several Chinese languages:

Mandarin, Beijing: Wo ai ni
Mandarin, Southwest: Ngo ngai ni
Minnan, Taiwan: Gua ai li
Wu, Shanghai:
(1) Ngu oi nong
(2) Ngu huoe-xi nong
Hakka, Meizhou:
(1) Ngai ai ngi
(2) Ngai jung yi ngi
Yue, Canton:
(1) Ngo oi nei
(2) Ngo jung yi nei

The word for &quot;love&quot; in the second variant in Wu is &quot;歡喜&quot;; in the second variant of Hakka and Yue it is &quot;中意&quot;. They are considered somewhat less serious than &quot;愛&quot;.
