CD is a good place to learn Sichuan dialect.(Let me do a little bit of propaganda for SC hua here, I’m very ya jian by the way, lol). Sichua hua is the 10th largest language in the world (if counted as an independent language, according to wikipedia), and SCH once almost became official language of China (1955 voting from a conference held by China’s character reform commission and ministry of education, Beijing hua has 52 vote, Chengdu hua has 51 vote, 1 vote difference make Putong hua base on the dialect of Beijing). when it comes to movies, if the director put SCH inside, it will make the movie very popular (my own opinion), such as Let The Bullet Fly (the highest box office Chinese movie until now, whole movie is in SCH) or Crazy Stone (cult movie, which was a national phenomenon in 2006). and SCH can also be used to communicate with people from other southwestern provinces. So, highly recommend you to learn SCH, cheers!
