Feimaonyannichuan
Feimaonyanniichuan is the Spring of Drowned Tam-girl. A Tam is a cat with wings, basically. This spring has yet to be accessed, so there is not much known about it. Those who dip in its waters will likely end up with a tail like a cat and wings on their back (likely smaller wings). They might also acquire cat ears and fur, though to what extent is always up in the air.
