In fact, it is not difficult, just like learning a foreign language, but it is much simpler than a foreign language, because after all, it belongs to the same language and is just a dialect. The simple way to watch Cantonese movies, documentaries and TV plays is to follow them, and you must say that if you can find some Cantonese friends to communicate in Cantonese, it should be faster.

Another way is to attend training. Now some foreign language training centers also provide Cantonese training. For example, this foreign language training center (/yyu.htm) is the Cantonese training page of Jinjilie. Actually, I don't think it's worth spending 700 yuan on this class. Why not spend 700 yuan to learn a small language? If time is not urgent, you can teach yourself slowly, so I still suggest self-study. Here is a website for self-learning Cantonese, which is better to teach from the aspects of phonetic basis, some Cantonese materials, input methods and so on. /yykt/yypy.htm
