In the present kuaishu [fast tale] there is no mention of textual unit, but extra-textual evidence indicates that the unit of this genre should also be considered a hui. In other pieces of kuaishu one finds occasionally the stock phrases biao yi hui 表一回[let me perform in this session] or shuo yi hui 說一回 [let me tell in this session], cf Chen Jinzhao 1982: 260, 278.
