How to evaluate Zhang Yimou's film Above the Cliff?

There is a foreshadowing in the plot, which paves the way for the following things, but when I want to guess the next plot, I find it is not my logic, which is a bit interesting.

In the end, there was a reversal. Lao Zhou is our party's undercover in the enemy, trying to protect Lao Zhang Xiaolan and Wang Yuchu Liang. However, he is also suspected, and may be found at any time. Walking on the tip of the knife, the final result is very thought-provoking.

The two-hour movie, the previous things have been explained, and the most important task, Operation outrat, was simply completed. Just for the protagonist to live to the end.

The details are handled in detail. Most of the guns used are Soviet pistols. Unlike modern pistols, gunfire obviously has a metallic echo. The interval between gun explosions is not so short, the action is also very practical, and there is no heinous protagonist aura.

My friend said that the ability of the hostess was greatly exaggerated. I feel good. At first, the hostess was inexperienced, hesitant, afraid to make moves, and her psychological quality was not strong. It's hard to kill a spy with people behind. Avoid being chased by spies and knocked down by spies, which proves that the female host is not as strong as the boy. Survival depends more on luck and the training of agents, psychological quality, and the cover and sacrifice of others. During the period, when Zhang and Xiaolan were avoiding the pursuit, Lao Zhang was protecting Xiaolan, reminding her to pay attention to the details and not to be discovered by the enemy. Xiaolan is also in this process, her psychological quality is constantly improving, and she is more calm when she meets things. I chose Xiaolan to participate in the action because of Xiaolan's special memory.

The last time we met in the war zone, it was also a pre-arranged protective measure, so that Xiaolan could meet Lao Zhou safely and complete the task.

Wang Yu and Chu Liang believed the two men who came to meet. With Zhang's help, they reversed their thinking on the train and guessed that the two people who came to meet were spies. Later, under the protection of Lao Zhou, Wang Yu began to flee. While driving, Wang Yu was hit by a spy and could not drive smoothly. A male spy can shoot while driving, but she can't. Fortunately, she was finally saved by Chu Liang, and Chu Liang died because she was injured and could not escape.
