Learning Cantonese can be lots of fun and romance.
When I saw this video on Youtube, I can't help thinking of putting it here to share with you and teach you how to propose to a girl like Jacky Cheung,
At 0:26, he said, "求求你“ means "I'm begging you." Now you know to beg/ask/request someone to marry you in Cantonese.
At 0:29, he said, "请姑娘你听埋佢我呢句” = Please, young girl, you listen to me to finish this sentence (Please let me finish my sentence.)
Note that the subtitle in the video is Mandarin translation, not Cantonese. That's why there's difference.
At 0:50 "字其实只得三个” = the words are only three characters
1:00 我爱你 = I love you! Note: 妳 = 你 nei2, but it is used for female.
