On October 16, 1964, my country’s first atomic bomb was successfully detonated in Lop Nur, Xinjiang, China, making China the fifth country in the world to possess nuclear weapons after the United States, the Soviet Union, the United Kingdom, and France. The official codename of my country's first successfully detonated atomic bomb is "Lao Qiu", and her nickname is "Miss Qiu". In addition, she also has the name "596", which is also called "the bomb".
In June 1959, the Soviet Union "suspended" the provision of nuclear weapons samples and technical data to China in order not to affect the Geneva negotiations on the Nuclear Weapons Test Ban Treaty between the leaders of the Soviet Union, the United States, and the United Kingdom. And as relations between the two countries deteriorated overall, on July 16, 1960, the Soviet Union stopped implementing the agreement to assist my country's solar energy industry and defense industry, withdrew all experts in China, and terminated the supply of all equipment and materials originally planned.
The Soviet government unilaterally tore up the agreement on new national defense technologies signed by China and the Soviet Union, and refused to provide China with atomic bomb samples and technical data for the production of atomic bombs. So in this environment, the Central Planning Department decided to start developing nuclear weapons on its own, and called this plan 596 Project.
In order to maintain confidentiality and facilitate naming, it has become a common practice to give atomic bombs alternative names. For example, the first atomic bombs of the United States were called Slim Man, the ones dropped on Hiroshima and Nagasaki were called Little Boy and Fat Man, and the Soviet Union’s first atomic bomb was called Little Boy and Fat Man. An atomic bomb is called a pumpkin. So the codename of my country's first atomic bomb was Miss Qiu, and the container containing the atomic bomb contained many cables and dozens of detonators. It looked like braids, so it was called a dresser.
Then the entire set of code words of the 596 Project were named after this. For example, when the atomic bomb was officially exploded and tested, the code word was Lao Qiu; when the atomic bomb was assembled, the code word was dressing; when the atomic bomb was in the assembly room, the code word was living in the lower room. ; The atomic bomb is in a sealed workshop on the tower, and the secret word is to live in a house; the atomic bomb is plugged into the detonator, and the secret word is to comb one's hair; the secret word of weather is blood pressure; the secret word is zero hour when the atomic bomb is detonated.
