Looking for dance classes in Beijing

Hello everyone,

I'm an German expat living in Beijing since 1.5 Years.
So I'm not completely new to Beijing and have quite some experiences to share  .
Lately my Girlfriend and I are looking for some couple dancing classes (e.g. Salsa, latin, standard...).
In Germany there was always a very broad range of offers regarding those, sadly here I couldn't find anything except very expensive Salsa lessons .
Does anyone in this Forum have some experiences with dance schools which offer such classes (optimally in English ).
Or know a place I could ask?

Thank you all very much for the information :-)
And it's great to be in this Forum!

Best regards styx
