掲示板 Forums - Renshuu for Chinese?

I really, really, really love Renshuu, and it has helped my Japanese a lot. So much, in fact, that my Chinese, my actual minor that I attend classes for, is starting to suffer. Does anyone have any platforms with features similar to Renshuu? I especially love being able to make my own decks with a dictionary attached, but I'm open to anything. I saw a post like this before but it was pretty old, so I thought it might be worth asking again.

I also was searching for similar apps for Chinese, and one that seemed the most alike to me was Ninchanese. Probably you will find it helpful
