Let's talk about the artillery during the Kangxi period. At that time, it was used to deal with Zheng Chenggong's attempt to recover Taiwan Province Province. It comes from Holland, and Zheng Chenggong's cannon comes from England. At that time, the Netherlands was naturally a member of the world powers, with superior strength in all aspects. Therefore, naturally made artillery was also the key factor for the Qing government to defeat Zheng Chenggong at that time. Therefore, at that time, all our guns were imported, and it was normal to be strong.
Let's take a look at where our firearms came from during the Opium War. Because we didn't have the money to pay the final payment, many guns used at that time were dumb guns, so our military strength could not be compared with that of the British. The British can make their own shells. At that time, we were still in the era of cold weapons, and naturally there was no way to alleviate this situation. The final result was failure.
Of course, there is another reason. At that time, during the Kangxi period, Manchu and Han fought with similar routines and strategies. They fought according to the ideas of China people. However, during the Opium War, China and Britain fought, and our hardware facilities were not good. It is definitely impossible for people on horseback to defeat countries that have used artillery for a long time, which will eventually lead to the weak combat effectiveness of the Qing government.
