The question is how to justify the use of fly in “the Flying Dutchman”.
It confused me for a long time. The right word could be wander, sail, roam, drift, but why fly? I looked it up the dictionary, and didn't find any meaning of fly that qualifies here, and I have never seen the word fly used like that anywhere else.
Can I say:
The Hukou policy in China made me homeless in my home country. For the years I just fly.
It feels so weird. “I just roam” or “I just drift” sounds better. The only case I can find of using fly to mean roaming is in the movie Up In The Air, where roaming literally means flying.
