We absolutely love PandaTree! I had my 4 year old daughter enrolled in a Chinese immersion preschool in person that was very costly for the fall, but due to the pandemic, we decided not to continue with that program. A friend introduced us to PandaTree and my daughter loves it! We enjoy having the option to read the bios and choose our teachers, but our favorite is Ying-Sin. She is super fun and engaging, often follows my daughters lead if she goes on a tangent from the lesson, but always continues to teach her along the way, and she is excellent at adding all mentioned words on my daughter's word list so that we can continue to practice together long after the lesson is over. I wish they were able to recruit more Taiwanese teachers, but in the meantime, we are very happy with the classes and Ying-Sin's availability. I appreciate that there are also little games and videos that make her want to use the program as well. She's been taking classes for almost 2 months now, but her Chinese has improved immensely and I'm excited for her to continue on this learning path. Highly recommend!
