The past and secrets have been revealed, and they have been asked for forgiveness... Wang Yan and he were small, classmates, comrades-in-arms, partners, and later together in Africa, Wang Yan replaced Xie Jian, who was stepping on a landmine, but Xie Jian ran away...
The film is two and a half hours long, starring one person, and the whole story is shot to the end. The film's frames are also getting smaller and smaller, foreshadowing his fate to go to a dead end, getting narrower and narrower; the film's transition from black and white to color indicates that he is really beginning to face the past; the recurring poster "The Tip of the Iceberg" indicates that he has too many secrets, and what is shown to people is only the tip of the iceberg. I think it's similar to the movie "Mints", is life a wrong step or a wrong step? Is it "especially late to make up for the dead sheep"?
Throughout our lives we are all hurting others to a greater or lesser extent, or being hurt by others. "Put down the butcher's knife and become a Buddha", human nature is not good or bad.
Charging for 5 minutes and talking for two hours is definitely true!!! The scariest part of the film is that the clock on the wall never goes; Wang Yan said in the call that the chance of demolishing the infantry mine is one in a thousand.
