You have to talk to others, not just listening. Just talk more and it will be fine. But I went to school out of town, and my classmates in the dormitory listened to my phone calls for a semester, and they were able to roughly guess what they meant, haha.

Take a look at several programs on Wuxi TV. They are spoken in Wuxi dialect, such as Afu Liaozhai and Onion Talking about Jintou. Although I don’t like these programs very much, if you want to learn Wuxi dialect It should still be useful.

There seems to be no shortcut to learning a language other than listening more and speaking more, right?

Haha, I wish you can learn it soon.
