Tu'er Ye is a rabbit with a human body adorned with the accouterments of an ancient general. Legend has it that, a long time ago, the rabbit sent by Moon Goddess once saved people who suffered from an epidemic in Beijing. Considered an icon of Beijing local culture, it was once used for worship as part of the festival tradition; now, it is mostly used as a type of decoration and a toy for children.
