How do you say chocolate milk in Chinese?

Cantonese:

我喜歡巧克力.
This is how it is written.
我 - I (ngo)
喜歡 - like (hay foon)
巧克力 - chocolate (ju go lick) The "ju" sounds like the "ju" in "juke".

But 喜歡 can also be substituted for a different but much more common way of saying "like". It doesn't have a written form, but it is pronounced "jong yee".

So it can either be:
"Ngo hay foon ju go lick" or "Ngo jong yee ju go lick".

Mandarin:

Mandarin only has one way to write it and verbally say it.

我喜歡巧克力 (Wǒ xǐ huān qiǎo kè lì)

我 - Wǒ

喜歡 - xǐ huān

巧克力 - qiǎo kè lì
