In this movie, Han () is a female warrior. Because she has a good relationship with Xu, she was locked in the opposite place by Zhang.

After the fourth counter-campaign against "encirclement and suppression" in Hubei, Henan and Anhui base areas failed, the Red Fourth Front Army had to leave the Soviet area. When the Red Fourth Front Army entered Kangjiaping and Renling areas in Manchuria, it was in trouble. Xu took the time to deploy a battle plan, decided on the intensity of Manchuan Pass, and finally succeeded in breaking through Manchuan Pass, and Han Ruolan was also released.

Film plot evaluation:

The film "A Bloody Battle at Manchuan Pass" is based on the failure of the Kuomintang's fourth counter-encirclement, and tells the story of Xu leading his troops over Manchuan Pass when the Red Fourth Front Army was chased after being intercepted.

Based on real historical events, it shows us that it is not easy for revolutionary predecessors to establish red base areas, which makes the audience deeply realize the cruelty of war, and also shows the determination of the older generation to sacrifice their lives to defend the motherland for their beliefs. It is a rare domestic conscience film.
