I learnt dutch for 18 months, certainly had a similar experience, although it's slightly better than 哈萨克语 (no sure how to say it in English :-) ). But I think if you search for local TV channels or contents in YouTube, you might be able to find something really useful.

I see. Yeah I guess Dutch is slightly more popular than Kazakh. How did you learn Dutch? I had to create a lot my own materials for kazakh.. because there is basically only one textbook and a Russian app for learning Kazakh.. But I think it's very cool to study less popular languages! :D So I definitely want to keep learning it.

Tobias, here are a few resources which I suggest you try them out --

1. iTalki.com which can help you find some native speakers for language exchange (German and Kazakh). Using this app, I found quite lot friends for language exchange. It's a very rewarding experience. Probably gave me the best motivation for learning a foreign language.
2. Search for a Kazakh TV station or podcast. I watched almost everyday a Dutch news channel for the local kids, which explained the current affairs / news to kids using very simple words
3. Contents in YouTube All the best with your language study! Feel free to buzz me if you need any help with Chinese.
