What is the impact of North Korea's nuclear test on China? Please talk to the analyst! thank you

Nuclear weapons are different from other weapons of mass destruction. Any country or organization, even individuals, has strategic influence. As far as North Korea is concerned, I personally think that the disadvantages outweigh the advantages. First, the possession of nuclear weapons by any country is a threat to other countries. Whether enemies or friends now, there are no eternal friends and enemies between countries. Second, the examples of India and Pakistan have clearly proved that the hope of defeating each other with nuclear weapons is basically self-destruction. The United States encourages India to develop nuclear weapons with the intention of containing China. From this point of view, it achieved its goal to a certain extent, but then Pakistan followed closely, and everyone saw the later results, but there were two more nuclear powers on the earth, which increased the possibility of nuclear war. Of course, under the premise that the government is stable and strong, the people of nuclear countries are living at the critical point of nuclear war. Although there has never been a real nuclear war around us, it is so easy for war to happen and even death to come. Therefore, the denuclearization of the peninsula is not China's weakness, but a basic principle that all mankind should realize and reach, and this principle is also applicable to any non-nuclear country. I grew up to protect my own safety, and so did I when I was older.
