There are two main configurations of hydrogen bombs, one is used abroad, and Yu Min of China invented a configuration, which is called "Yu Min Configuration" for short. Therefore, there are no hydrogen bombs abroad so far, while China's hydrogen bombs are "deployed by the people", so they can be preserved for a long time, which is why only China has hydrogen bombs at present. As for how much Yu Min has to do with the hydrogen bomb, here you are.
There are only 30 hydrogen bombs in the world, all of which benefit from the long-term preservation of sensitive structures. And these hydrogen bombs are all from China. Therefore, China's hydrogen bomb level is the first in the world. No country has more hydrogen bombs than ours. Anyone who refuses to obey us can fuck him with a hydrogen bomb at once.
From the breakthrough of atomic bomb to the experiment of hydrogen bomb principle, if we look at the time, we only spent two years and eight months, while Americans spent seven years and three months, the former Soviet Union and Britain spent four years and three months, and France spent eight years and six months. Moreover, our development conditions are relatively more difficult. The reason why we can make such a breakthrough so quickly is largely due to the wisdom and selfless dedication of the older generation of nuclear workers such as Academician Min.
