《乐工罗程》是借乐工罗程杀人获罪的故事,说明执法必严的道理。作者在文中虽未加议论,但全义主旨鲜明,褒贬之情溢于言表。文章达到这样的艺术效果,和作者精妙的构思不无关系。他围绕主题,权衡损益, Luo Cheng, a musician who has been convicted of murder by Luo Cheng, demonstrates that law enforcement must be strict. Although the author did not add discussion in the text, the whole meaning of the subject is clear and the sentiments of praise and demeanor linger. The article achieves such artistic effects and is not unrelated to the author’s subtle ideas. He revolves around the subject and weighs the gains and losses.
