Then there is the Opium War. According to the current understanding of international law, one country does business with another country, but that country doesn't tell you its laws at all. It sent troops to take your goods and destroy them without a court hearing or judgment. Although this kind of thing is opium, you should know that the bulk of the opium trade tax revenue was taken away by the Qing Dynasty. Then Britain sent diplomatic envoys to discuss how the Qing Dynasty compensated you. However, local officials and the imperial court took the British as a big head, and no one came out to give a statement.
If you are a strong army in the Qing dynasty, you will be recognized if you can't beat the British. It happened that the Qing dynasty was incompetent in military affairs, and you fell down as soon as you hit it. You are unreasonable in the Qing dynasty and your strength is not good enough. It's really unreasonable not to do it. Therefore, at that time, the two Opium Wars were self-inflicted by the Qing Dynasty, mainly because the people were unlucky.
