Here is a very nice learning website for children who already speak and understand Mandarin Chinese. You can listen to Chinese stories on www.childroad.com
Go to the homepage, click on the FREE sample and choose the books you like to read and listen to. There are over 10 books available in the free sample selection. The Mandarin Chinese pronunciation is accurate and the recording has good audio quality. Stories are written in simplified Chinese characters with pin yin. There is no English translation or subtitle available.
My 6-year-old daughter enjoys listening to the stories and she gives it a Very Fun Happy Face rating. Miss Panda also gives CHILDROAD website a Happy Face rating for its quality and content.
