I actually want a tongue twister for practice. But I want one that could be a Chinese sentence. Is the following at all acceptable as way to say "This is the 'seek truth through facts' rock"?
By that I mean the rock on the Renmin University campus with the motto 实事求是.
On line I find nearly this, but always with 石额 or some other noun complement to 石. Can I possibly do without that, or is 石 too much of a bound morpheme to allow that?
