Undefeated background creation

In order to shoot the film, the film crew was stationed almost at the school. The film crew wakes up early every day, and they work out and eat together with these athletes. Athletes are learning, and the film crew is also filming. Whatever the athlete is doing, the camera crew will record their movements and actions. Over time, the film crew and these athletes became friends and entered their lives. Their fighting spirit moved the director, so the director thought in his mind whether to express this fighting spirit as the theme of the film   .
