The E16/E17/E18/E19/E20/E21/E22/E23/E24/E25/E26/E27/E28 entry of Tangshang Naga [nst] subsumes varieties which are not all mutually intelligible ( Stephen Morey 2015 ). In particular, the varieties of Champang, Chambok, Lumnu, Haqchum, Longpan, Tokhe and likely also Nahen may be separated out for its own entry ( Begum, Asifa 2022: 218 , van Dam, Kellen Parker 2018: 88-94 ).
