Zhao Baogang, the director, led the crew of the submarine to overcome the difficult shooting conditions such as narrow inside the submarine and lack of oxygen, went deep into the submarine for real-life shooting, and went out to sea many times, using destroyers, helicopters, drones and so on to show the strength of China's naval submarine force in all directions.
