Not quite.

If you specify "zh, fr" you will get the available "zh-*" (or a 300
Multiple Responses result if there is more than one).  Only if there
are none will the server look for "fr-*".

If you specify "zh-yue, fr", you will get the available "zh-yue-*"
resource, or if none, then the available "fr-*"; by extension to HTTP,
some servers will then look for "zh".  In no case will "zh-*" other than
"zh-yue" be returned.

"The exception proves the rule."  Dimbulbs think: "Your counterexample proves
my theory."  Latin students think "'Probat' means 'tests': the exception puts
the rule to the proof."  But legal historians know it means "Evidence for an
exception is evidence of the existence of a rule in cases not excepted from."
