don't rely on Wiki at all...
Cantonese is a lot more harder than Mandarin in my opinion ;)
I took 2 years to conquer in Mandarin; Cantonese?
Even My mum is a native speaker of Cantonese, a HongKonger, and she teaches me to speak and to use the phrases...I'm still confused, and i speak with lots of ''lazy sounds''...
You needa be very careful with your pronunciation; people might easily get confused for what you've said.
