 In her analysis of Yangzhou storytelling , Børdahl noted that the aforementioned tale about Zhou and Wu Song uses different forms of dialogue for both characters . Wu speaks square mouth utilizing standard mandarin without rusheng ( short glottal syllables ) . On the contrary , Zhou speaks squaremouth using the Yangzhou tone system , which does utilize rusheng syllables . Therefore , she believes " square mouth dialogue should at least be divided into two subcategories , namely the Wu Song variant — without rusheng , and the Zhou Tong variant — with rusheng " .
