Learn Chinese Pinyin – intended for Chinese children
I think it is a interesting video, it is intended for children to learn Mandarin. So they talk in Chinese with each other already, that is also the reason I put the video to advanced level. They learn Pinyin, starting from scratch with lively games. There is a child for each letter in the game. You can also see the exact form of the mouth.
For the user with better level it is a good video to follow words from the teacher, she speaks slowly for the children, however it is certainly not so easy for non-native speakers. Just try it!
This time they also go through many examples for the initials.
