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 use many examples for the initials.
This video (see at YouTube) is of advanced level difficulty. It has subtitles in Pinyin and Chinese characters. Note it may be especially suited for kids. We especially recommend this video.
