As a Cantonese song lover, I always try to learn Cantonese by myself. When I saw this course planning, I realized that If you want to learn something well, you have to learn it systematically. I like the topics. They are pretty much the most important components of learning a language. I believe this course will help learners well. As pod 9 mentioned  in the learning resources, both Mandarin and Cantonese are in in the same language system. So I think maybe this course require learners know Mandarin. And like some of the PAAS courses, instructors give lessons and learning materials in Mandarin. So I am thinking maybe the better way to teach this course is give all the lessons and accessible materials in mixed of Mandarin and Cantonese.
