In the play, Zhidan Su, a senior cadre, led Liancheng to the revolution and directly arranged Liancheng to lurk for a long time until Liancheng grew from a fugitive to a general. In real history, there is also a comrade named Zhi Dan who cares about and guides the growth of Han Liancheng. His name is Liu Zhidan, and he is one of the founders of the Red Army in northern Shaanxi.
During the period of 1926, Liu Zhidan got to know Han Liancheng during the military transportation work of the Northwest Army, and made him receive communist education. In this play, the names of Zhidan Su and Liu Zhidan collide.
If Zhidan Su didn't meet Liancheng in Nanking at last and sacrificed a play in a teahouse, people would think that the prototype of Zhidan Su was Liu Zhidan. But it is unreasonable that Liu Zhidan can't do such a job. Besides, it seems that Liu Zhidan didn't live to the war of liberation, which is a specious and unreasonable structure.
Extended data:
Zhidan Su is a senior cadre among the invisible generals of the Communist Party of China, in charge of intelligence work and an invaluable guide.
After being killed by the enemy Han family, the wealthy businessmen in the northwest were loyal to each other and fled to the Kuomintang, but they accidentally met Zhidan Su, a member of * * *. Under its influence, he established a belief of loyalty to * * * *.
In a melee, Liancheng unexpectedly rescued senior Kuomintang officials, thus making rapid progress. At the same time, under the code name of "cold wind", he lurked inside the Kuomintang to collect information for our party. Han Kui, the son of an enemy North Korean parent, became the head of our party's Qiongya detachment and sneaked into the national army for a pretence.
Liancheng and Han Kui's feud know each other, but they don't know each other's true identity. They kill each other. Han Kui's step by step, Zhidan Su's sacrifice, and the rebellion of underground party member Quxin, who mastered the joint code, made Liancheng gradually fall into danger, but he still took risks and used his special status to make our army successfully encircle the national army and constantly send top secret information to our army.
When his identity was finally exposed, Han Kui, who knew Liancheng's true identity, sacrificed himself to cover Liancheng's safe retreat.
