I was looking for a suitable video of the story to show the pupils in my Mandarin club and came across this version in English which is attractively illustrated.
I also found a song about the animals of the Chinese zodiac (十二生肖歌 shí’èrshēngxiào gē). It has a catchy refrain in which the Chinese for the animals of the zodiac are repeated in order – useful for fixing this in the mind! This version is in pinyin and is relatively easy to follow, although the last word doesn’t match with what is sung. This other version is slower, has images of the animals and the meaning of the song, but otherwise is just in characters, so not so suitable on its own for my KS3 club. However, I’ve done a transcription in characters and pinyin for use with beginners.
