《新唐书·列传·卷一百二十一》
一匹是红鬃白毛，有龙的骨骼、凤的仪态，奔驰起来像舞蹈，整天被役使而热死；另一匹则是大头翘尾，颈似驼、膝如貉，踢咬尥蹶子，被丢弃在野外，全年都长得肥壮。
将行，赐隐居服，官营草堂，恩礼殊渥。鸿到山中，广学庐，聚徒至五百人。
One is red mane and white hair, with the skeleton of a dragon and the demeanor of a phoenix. When galloping, it looks like dancing and died of heat after being used for a whole day. The other one has a big head and a raised tail, a neck like a camel and knees like a raccoon. It kicks, bites and bucks. It got abandoned in the wild and has grown fat all year round.
