0 1. Self-improvement, independence, and persistence in developing nuclear submarines. In the early days of the People's Republic of China, China's economic strength and scientific and technological strength were not well recovered and developed. But if you are not strong, you will be bullied. For the development of the motherland, at this time when the country is employing people, Huang devoted himself to the cause of science and technology and worked with the scientific research team to develop nuclear submarines. However, without core technology, it is always difficult to develop. Especially after the rigid relationship with the Soviet Union, without the technical support of the Soviet Union, the research and development of nuclear submarines at that time was dealt a heavy blow, which made matters worse. However, Huang Xuhua did not give up the nuclear submarine business, but made greater efforts to lead the scientific research team to continue developing nuclear submarines.
02. Struggle for the cause of nuclear submarines regardless of the harsh environment. A country has the guarantee of scientific and technological strength, and it has the security guarantee in the face of war. On the contrary, national security will also be threatened. Nuclear submarine technology is very important to the country. Huang Xuhua, for the research and development of nuclear submarines, once led a scientific research team to concentrate on research and development in places with harsh environment. In order not to let the scientific research results leak out, no matter how bad the environment is, they choose to stick to it.
03. Leave the person you love. For the research of scientific research and nuclear submarines, Huang Xuhua led the research team to live in places where their families could not find them. Even his parents and wife don't know what he does, and they can't see him. I never saw him before I died.
