梧桐树林的猫女巫
[wú tóng shù lín de māo nǚ wū]
This nickname depicts a fantastical scene where a magical cat resides within a forest of parasol trees (or Phoenix Tree). There is an ethereal charm in this setup as Chinese folklores tend to associate cats with supernatural beings. Therefore the author likely wishes themselves being a mysterious witch figure living amidst nature's serenity and enchantment.
