In Shanghai I stumbled across caged wax eyes for sale on a street corner.
It was unnerving to witness one of our beautiful natives, tauhou, sit nervously imprisoned in neat, bamboo enclosures.
As a traveller in a strange land, it raised a few interesting questions. Namely, whose birds are these?
Here, they're classified as a native. Which, of course, doesn't preclude also being native to China, or any other territory they may have landed without the help of man.
If they're not native to China, then they're exotic in that country, and therefore in the People's Republic would occupy the same category to that of a caged budgie here. To be native, is relative to where you're standing.
