How do the Japanese view Manchu's entry into the customs and what impact does it have on Japan?

There are no eternal friends and no eternal enemies. Friends or enemies need to be judged according to the current political events. At that time, Japan had two main sources of intelligence. The first place was a mainland merchant ship that visited Nagasaki. Their intelligence is very fast. In such a difficult environment at that time, it was only a month before they wanted to receive the news. Therefore, Japan attaches great importance to this intelligence work.

Chongzhen died on1April 25th, 644. /kloc-On May 25th, 2000, Qing soldiers entered Beijing, and the Japanese side received the news as early as June 3rd. In just over a month, the news spread from Beijing to Nagasaki. In the era of underdeveloped information in the past, it was also fast. At that time, in order to cope with the Ming dynasty, the Qing dynasty adopted a friendly policy toward Japan in order not to increase the number of enemies.

The fact is, the Japanese attached great importance to reality and soon learned that the Manchukuo army was very strong, thinking that only a fool would do that when the Japanese threw stones at eggs. Nan Ming did ask Japan to send troops many times. Zheng Chenggong, who is half Japanese, strongly hoped to transfer Japanese soldiers, but the Japanese soon realized this situation and gave up the idea of supporting Nan Ming.

In fact, Manchu's entry into China and Japan's invasion of China belong to the same nature, both aggression and aggression against the country, but there are still essential differences, that is, Manchu is a part and Japan is a foreign population. The Japanese still have a sense of crisis about the entry of the Qing Dynasty, because they have a strong opponent, and it is not certain who will win this battle. From a historical point of view, the Manchu Dynasty has advantages to some extent, because they belong to us.
