Modern militarist Japan committed unforgivable war crimes against China, but in 1645, Japan was a small China in the eyes of Chinese readers, a cultural circle, and it was very close.
The Japanese also called the Han regime's China the Chinese concubines, and they were shuzi, and they were proud of them. After the Manchu Qing Dynasty entered the customs, there were calls in the ideological circles in Japan that Emperor Shuzong had difficulties, and Emperor Shuzong should be saved, and he must not let the Tatars destroy the Chinese branch.
At a critical juncture, the Southern Ming regime also turned its attention to Japan in the east.
The first was when the Qing army occupied Hangzhou, when Zhou Hezhi, the governor of the Southern Ming Army, sent emissaries to the Satsuma Domain in Japan to ask for help.
In the following two years, the Southern Ming regime sent regular missions to Japan three times to ask for help, but unfortunately did not get a response from the Japanese side.
Due to the sharp turn of the anti-Qing situation in China, the Nanming regime sent three groups of missions to Japan to ask for help on several occasions without responding.
This is no longer a request for soldiers, but a request for soldiers.
On one occasion, the famous great thinker Huang Zongxi was also in the mission, and he was still on an envoy as the deputy imperial history of Zuo Du.
The last envoy to ask Japan for help was the great Confucian Zhu Shunshui, but still did not succeed. After that, Zhu Shunshui saw that there was no hope of restoration, so he stayed in Japan and became the guest of honor of Tokugawa Mitsukuni, the lord of Mito Domain. However, japan's internal opinions are not unified, and after fierce debate, the two sides believe that Nanming has become hopeless, and finally abandoned the large-scale dispatch of troops to rescue Nanming.
Although later, under the mediation of the national surname Zheng Chenggong, some Japanese lords privately sent some small reinforcements, but for various reasons did not succeed.
