《狼烟北平》情节以两条主线穿插而进行，国共两党的地下工作人员在不同时期的合作和较量是小说一大主线。特务工作的神秘、刺杀锄奸的惊险、严刑审讯的惨烈、革命加浪漫的爱情、荡气回肠的死亡，环环紧扣、极尽质感。底层人物及其生活是小说的另一条主线。中国现代作家，描写北平引车卖浆之徒的高手当是老舍先生，其地位数十年无人能撼。但是晚生后辈都梁来了，也写人力车夫，写天桥，写蟋蟀蛐蛐儿，写茶楼小吃。市井俚语之粗鄙，泼皮无赖之本相，国民心理之隐忍之麻木之自私之丑陋，被暴露无遗。（This book has two main lines: one is the cooperation and struggle in different periods between the underground personnel of KMT and CPC. The secret service is mysterious, elimination of traitors is thrilling and interrogation with cruel torture is horrifying. The revolutionary and romantic love and soul-stirring death stick closely with each other with extreme texture. The other line is the lower-class people and their lives. The master who describes the ordinary people best among the modern writers in China is Lao She, whose position cannot be replaced with other in decades. But Du Liang, the younger generation, who also describes rickshaw puller, Tian Qiao, cricket and tea house and snack. The vulgar slangs in the marketplace, the true features of ruffians, the numb, selfishness and ugliness of the national psychology are completely exposed.）
