The semantic basis for the co-occurrence of evidential adverbs and ba is"non-actuality".Categorial similarity is a prerequisite for co-occurrence,and differences in the de-gree and direction of conveyance are observed in co-occurrence,which is the main factor re-stricting the ability of multiple conveyance methods to coexist.The"necessity meaning"has stronger evidentiality than the"possibility meaning",and the degree of information knowl-edgeablility is higher than that of the"possibility meaning",which leads to weaker co-occur-rence ability with ba.The co-occurrence of evidential adverbs and ba is mainly used in dis-course sequences where there is asymmetry in the epistemic status of the participants.In in-teraction,both parties will adjust their epistemic status(downgrading or upgrading)based on the needs of expression and communicative intent in the context,or deliberately violate the information domain using the"evidential adverb X ba"construction and adopt an"out-bound strategy"to conceal their true epistemic status,in order to achieve pragmatic polite-ness.
