However, at the time of the request, no published research existed establishing that Chung [cnq] and Mbuk [bpc] were varieties of a common language. Tschonghongei's 2020 thesis on Mbuk now provides evidence that each should be treated as a separate language, which is why we now request a code for Mbuk.
