Zi Jin: Yu Miao Fang

There are special creatures that live in the modern Forbidden City. By day, they're the idols of the Forbidden City, and a simple yawn can earn the squeals of the crowd! By night, they're the protectors of the Forbidden City who watch over the restoration of cultural relics! While they could've lived day to day on their cute appearances alone, they've chosen to bear the burden of preserving culture and safeguarding relics. They're the Forbidden City's Impurrial Cats!
