Got it. The documentation page also noted the following:

When searching, RefTeX will also expand recursive path definitions
(directories ending in ‘//’ or ‘!!’).

So, the "/home/werner/texmf/bibtex/bib/hongyi//" will let RefTeX do a
recursive path search under the "/home/werner/texmf/bibtex/bib/hongyi"
directory.
