Wu Qianli did not sacrifice in the ending of "Changjin Lake", but the film highlights indicate that Wu Qianli will sacrifice.

In the extras, Wu Wanli holds a letter from home in his hand. Wanli is set as a "wild child" who grew up by the river. He has never studied and is illiterate. It is the first time he holds a piece of paper. Writing is to write a review. Suddenly there was a scene where Qian Xi was looking at the paper in his hand, very seriously and with tears in his eyes. Although it was still the same look, it was a little more calm. ?

Look carefully, there is only a piece of paper in Wan Li's hand, and he is holding an "urn" in his arms. At the beginning of the film, Qianli brings the ashes of his elder brother Baili home, and this jar is in his arms. The paper in Wanli's hand should be the house drawing that Qianli designed for his parents, so Wanli kept staring at it. ?

The drawings designed by Qianli were also made public. It said, "If you can't come back, give the letter to your parents and let a literate gentleman read it." This was Qianli's instruction to Wanli. ?

"Water Gate Bridge" should be the second part of "Changjin Lake". In the second part, Wu Qianli should have died, and his younger brother Wu Wanli went home with his brother's ashes.

The Wu family has three sons. The eldest son Wu Baili and the second son Wu Qianli are away fighting, while the youngest son Wu Wanli stays at home. At the beginning of the film, Wu Qianli takes Wu Baili's ashes home, preparing to keep his home from now on. However, on the night of returning home, Wu Qianli was urgently recalled to participate in the War to Resist U.S. Aggression and Aid Korea. ?

The eldest son had already died on the battlefield. The Wu family’s parents watched their second son rush to the battlefield again without saying a word. It is not difficult to imagine how much sadness and uneasiness is hidden behind such silence - can my son come back now that he is gone? ?

The more silent his parents were, the more uncomfortable Wu Qianli felt - thinking of his parents' eyes when he left, he felt extremely complicated, feeling guilty and uneasy, but he had no regrets. In order to make his parents feel more at ease, Wu Qianli specifically asked his younger brother Wu Wanli to stay at home to take care of his parents, build a house, and marry a wife - because he knew that he might never come back. ?

As the commander of the first company, Wu Qianli carries a notebook with him, which contains the names of everyone in the seventh interleaved company. Most of these people have died. Whenever someone died, Wu Qianli would take out a small book and frame their names in red lines - he knew that only by winning this battle would he be worthy of those comrades who sacrificed their lives.
