Sorry for the very very late response.

I agree that "ling2" sould correspond to U+3007 rather than to the
current U+25CB (WHITE CIRCLE).  For the latter, if we dare to assign
some key sequence, it should be "wan2" (the key sequence for "丸" (the
meaning is circle)).

I don't remember why quail-ext.el has such a code.  As it is in
quail-ext.el, perhaps it was a request from some Chinese user.
