自明清以来“十三道大辙”和“两小辙儿”在北方的曲艺文学中,起着非常重要的作用。但是由于“小辙儿”音值的发展演变问题,以及“小辙儿”自身的使用范围的限制,现在普遍为大家所认同的“两小辙儿”的名目虽然沿用,但是它已经不能涵盖所有小辙儿的读音情况,未被提及的其它几小辙儿在曲艺文学中也同样被广泛使用。 Since the Ming and Qing Dynasties, “Thirteen Roads” and “Two Little Ruts” play a very important role in folk art in the north. However, due to the development and evolution of the value of “Little Rovers” and the limitation of the use range of “Little Rovers”, it is generally accepted by everyone that although the names of “Two Little Ruts” are used , But it can no longer cover the pronunciation situation of all the boys and the other few who have not been mentioned are also widely used in the folk literature.
