Second, in terms of the degree of specification of a scale, a two-point closed scale motion morpheme (e.g., jin "enter)" is not more specific than a multi-point closed scale motion morpheme (e.g., hui "return)", or vice versa: both specify the existence of a scale and the existence of an endpoint for the scale.
conforming to the Scalar Specificity Constraint, two closed scale motion morphemes do not co-occur, as in *hui-jin fangjian returnenter room.
