I'm the founder of hihilulu Chinese Immersion platform.
My team and I had worked on this project for three years. Our "Learn Chinese hihilulu" is on AppStore and GooglePlay. What we are trying to do is to create an authentic, natural Chinese language environment for young learners to acquire Chinese naturally and easily.
A lot of people consider that Chinese is a difficult language. I would say it is probably a "priority language" in this century, but not the hardest one if we explore proper methods.
Based on my own experiences and many studies, I believe the early we start to learn Chinese, the easier for us to master the tones, pronunciations, loan words, etc..
Let's watch this Video to see what we are doing here.
