- Pyngo.com 
The most difficult aspect of learning Chinese language is to "practice" what you have learned from classes or audio tapes, often referred to as "language immersion." According to the famous Russian psychologist Lev Vygotsky, "all cognitive function processes, including learning language, arise from social interactions." So, unless you have a socially interactive environment, learning a foreign language on your own is very difficult, no matter how committed you are.
Through Pyngo, you can connect with Chinese native speakers at any time and practice what you have learned from audio tapes or classrooms. So you can achieve that all important level of language immersion - for better learning, comprehension and speaking.
