What is the background music repeated in the poem directed by Zhang Ziyi in My Father and I?

The background music has not been named yet.

Poetry is directed by Zhang Ziyi, starring Huang Xuan and Zhang Ziyi. It tells the story of the silent dedication of an aerospace family behind the development and launch of China's first artificial earth satellite. This is a good topic. But what is puzzling is that the film actually follows the style of scar film and renders a cold and cruel tone.

Scar movies "created" a style, that is "occupation". Although the film tells the story of New China, the atmosphere is like an "occupied area", killing and danger. Everyone is full of hostility, and the protagonist may be in danger at any time.

Its characteristic is that the tone of the film has evolved from "occupation state" to "concentration camp state". Huang Xiaoming plays Chen Peng, a Tsinghua graduate who goes to work at the Northwest Nuclear Test Base like a prisoner in a concentration camp.
