There's a great website call Slow Chinese 慢速中文 which I found recently.
If you want to practice your listening skill, you definitely need to take a look.
The material is free and they speak really slowly!!! I'm currently learning
German myself, and also learning from a webpage called Slow German,
that's why I found this Slow Chinese by accident.
There are various categories for Chinese learners and it's free of charge!
I hope you find this information helpful :)
