I have produced a Youtube video entitled
Learn to read and write simplified Mandarin Chinese. [url=http://www.youtube.com/watch?v=mySwTPoFAhE]

Each character in a simple Chinese children's is shown with its stroke order, pinyin and tone. The voice is standard Mandarin by ZHENG Ruonan from Xian.
The English text is kept to a minimum.

The frames of the video were generated using vector graphics. This story and others will be available as PDF files where each sound bite can be played repeatedly on demand, and the image can be enlarged without loss of sharpness. The PDF files are suitable for PC and Mac using the free Adobe Acrobat reader (version 9 and newer), and on android tablets and phones using the ezPDF reader.

I am very interested in specific feedback to optimize the presentation of future titles.

Is a good idea.
