What do critics think of the novel Defending Yan 'an?

Critics believe that defending Yan 'an was based on the Yan 'an War in northern Shaanxi from March to September, 1947, when Kuomintang troops under the command of Hu Zongnan attacked Yan 'an and Peng voluntarily gave up Yan 'an and then recovered it. With a single ideological perspective and a continuous tense rhythm, the novel created fearless heroic images such as Tian Dayong, Li Cheng and Wang Laohu, and arranged adversity for the heroes to "test" their will to fight, retreat and bleed to death, so that the novel maintained a high degree of heroism from beginning to end. At the same time, an influential historical figure (here refers to General Peng) is positively represented as an artistic image, which is very rare in China's modern novels and has also attracted the attention of critics.
