According to the scenario, Chinese missile forces launch ICBMs on a conditional enemy in response to a strike on bunkers.
Intercontinental ballistic missiles are located in well-fortified bunkers in the mountainous regions of China. These underground structures are able to withstand the bombing of almost any kind of weapon or a collision with a passenger airliner. In addition to mountain bunkers, Chinese nuclear weapons are located on submarines and mobile platforms.
Engineer Qian Qiu received a high government award for creating a bunker system. His brainchild is called the "underground Great Wall of China."
In addition to simulating retaliatory strikes, exercises were conducted on long-term survival after the atomic bombing. All this suggests that China is seriously concerned about the exacerbation political situation in the world and deterioration of relations between nuclear powers, primarily between the USA and Russia.
