Dongying people refer to Japan, and the word "Dongying" first appeared in the Qin Dynasty of our country, when there was also a record of Qin Shi Huang in order to seek the elixir of life, sent the imperial doctor Xu Fu to lead 3,000 boys and women from the coast of Shandong to the east.

Nowadays, both in China and Japan, the legend of Xu Fu has been left behind, and since the Later Three Kingdoms, Jin, Sui, Tang, and Song Dynasty, there have been Dongying people who came to China to study and exchange.

After the Yuan Dynasty destroyed the Southern Song Dynasty, Kublai Khan used troops against Japan twice in 1274 and 1281, which caused the relations between the two countries, which had been close and friendly since the past dynasties, to turn into hostility.

The Mongol invasion also indirectly triggered a crisis in Japan, and with the fall of the Kamakura shogunate, a large number of samurai became ronin, and a large part of them became Japanese pirates, colluding with Chinese pirates and unscrupulous merchants to flow to the southeast coast to plunder and cause trouble, which became a major scourge in the southeast sea of the Ming Dynasty.

In the Ming Dynasty, Ming Taizu Zhu Yuanzhang urgently restored diplomatic relations with Japan after his accession to the throne, and one of the main reasons was also to hope that the two countries would work together to eliminate the "Japanese rebellion" and maintain peace and stability in the East Asian seas.

In the second year of Hongwu (1369), Zhu Yuanzhang sent Yang Zai to Japan with an edict to inform the news of Hongwu's accession to the throne, and at the same time condemned the Japanese for harassing our southeast coast, and ordered the Japanese side to strictly ban it and come to pay tribute as soon as possible, otherwise they would go out to crusade against Yunyun, and the tone was quite tough.

Due to Zhu Yuanzhang's lack of understanding of Japan's national conditions at that time, the envoy suffered a major setback. And it was precisely because the two countries did not understand each other, and Japan was in a period of chaos between the North and the South, that Zhu Yuanzhang's threatening edict aroused the common hatred and hatred of the Japanese, thinking that it was another prelude to the "attack of the Yuan Kou".

Prince Huailiang, who had been in charge of Kyushu for ten years, scoffed at Zhu Yuanzhang's edict, imprisoned Yang Zai, Wu Wenhua and other envoys, and killed five attachés.

As early as the second year of Emperor Motoshun (1336), the Ashikaga clan, who had entered Kyoto, deposed Emperor Go-Daigo and established another emperor, appointed himself as the general of the Seiyi, and set up a shogunate in Kyoto.

Emperor Go-Daigo fled south to Yoshino and established an imperial court, known as the Southern Dynasty in history, and the imperial court in Kyoto was called the Northern Dynasty. In order to restore royal power, Emperor Go-Daigo overthrew the shogunate and sent his son to set up a conquest of the Western Province in Kyushu.

In the twenty-fifth year of Hongwu (1392), the Northern Dynasty unified Japan. Zhu Yuanzhang never gave up his determination to surrender, and finally after hard work, Prince Huailiang's attitude towards the Ming Dynasty changed, and then sent the monk Zu to the Ming Dynasty to pay tribute to horses and goods, and returned more than 70 people from the coastal areas of Zhejiang who had been captured by the Japanese invaders.

On the surface, although the two countries have a close relationship, there are sometimes disturbances and other incidents such as "Japanese people". The unification of the Northern Dynasties, the warriors, politicians and ronins of the Southern Dynasties lost their support, so they fell to the sea, entrenched on the island, when they saw the abundance of materials in the Ming Dynasty, and tried to rob the Ming Dynasty of resources.

As a result, Shandong, Zhejiang, Fujian, and other coastal areas all had local nuisances such as burning, killing, and looting by "Japanese people," and they formed a considerable force that infested China's coastal areas from time to time, causing increasingly blazing Japanese troubles.

Ashikaga Yoshimitsu, the third shogun of the Ashikaga shogunate, who unified Japan, also wanted to purge the remnants of the Southern Dynasty and fight against pirates at sea, and at the same time wanted to develop trade with the Ming Dynasty and obtain rich benefits, so the two countries restored relations.

During the Ming Dynasty, the two sides established a trade relationship with the Ashikaga Shogunate, and the Ming Dynasty gave the Ashikaga shogunate a trade certificate, that is, the Survey, and the Japanese side came to China to pay tribute and trade with the Akin Shogunate.

The Ming Dynasty developed relations with Japan mainly to eliminate the incursion of the Japanese invaders into China's coastal areas, and the Ashikaga shogunate also actively suppressed the Japanese invaders.

After the death of "Ashikaga Yoshimitsu", his son "Ashikaga Yoshinori" changed his policy, the exploration and trade between the two sides was interrupted, and Japan no longer hunted down the Japanese invaders, and the raids of the Japanese invaders, which had been slightly restrained during the "Ashikaga Yoshimitsu" period, spread along the coast of China.

Later, during the "Ashikaga Yoshikyo" period, Sino-Japanese exploration and trade was resumed. In the third year of Seihua, the first year of Onin (1467), Japan entered the Warring States period, the Ashikaga shogunate weakened, and the Kanai trade system was destroyed.

After the Jiajing of the Ming Dynasty, Sino-Japanese exploration and trade were completely cut off, and the invasion of Japanese pirates became increasingly serious. At the beginning of the Ming Dynasty, due to the strong national strength and the importance attached to coastal defense measures, the Japanese invaders failed to cause serious trouble.

After orthodoxy, with the political corruption of the Ming Dynasty and the relaxation of coastal defense, the arrogance of the Japanese became increasingly arrogant. In the fourth year of the orthodoxy of Emperor Yingzong of the Ming Dynasty (1439), the Japanese invaded Taozhu Village in Taizhou, Zhejiang, killed people and set fires, dug graves and dug graves, and even tied the baby to a pole, poured it with boiling water, watched the baby's heart cry, and applauded.

The crimes of the Japanese invaders brought suffering and disasters to the people of the Ming Dynasty, and in the Jiajing period, with the further development of the commercial and trade economy in the southeast coastal area, foreign trade was quite developed. Maritime trade along the coast is also very active with individual businesses.

In order to make huge profits, some maritime merchants and Zhejiang-Fujian merchants disregarded the imperial court's order to ban the sea and sold goods to each other with the "Fanbo Yi merchants." They split up in groups to form armed smuggling groups at sea, and some even went overseas to collude with the Japanese pirates on various islands to plunder along the coast.

These pirate merchants, such as Wang Zhi and Xu Hai, colluded with the Japanese pirates, making the Japanese plague more and more intense and out of control. At the same time, some Ming bureaucrats also established contacts with these robbers.

In the twenty-seventh year of Jiajing (1548), the Ming Dynasty sent Zhu Juan to inspect Zhejiang, and also to supervise the military affairs of Fujian.

Zhu Xuan's sea ban violated the interests of the bureaucrats and wealthy people, and they instructed the bureaucrats in the DPRK to attack Zhu Xuan, as a result of which Zhu Xuan was slandered and forced to commit suicide.

Since then, the Minister of Inspectorate has not been set up, and the DPRK, China and the DPRK have not dared to mention the matter of the sea ban. The pirates became even more rampant. The heinous crimes of the Japanese invaders caused devastating disasters to the people in the coastal areas of the Ming Dynasty.

In the 31st year of Jiajing (1552), the Japanese invaded again, and more than 1,000 people were recruited from Nanhui County, Mindian and other places to resist the Japanese.

In the same year, the Japanese invaded Songjiang, and Sun Bo, a merchant in Yingzhou, subsidized military salaries, and sent people back to their hometowns to mobilize their children and nephews to participate in the anti-Japanese struggle. At that time, there was a saying that "Wuzhong leaned on the Great Wall".

In the thirty-fourth year of Jiajing (1555), the anti-Japanese army composed of Miao, Han, Zhuang, Yao and other groups of people, in the Ming Dynasty, the patriotic general Qi Jiguang, (north of Jiaxing) broke the Japanese and killed 2,000 enemies, which was a huge victory in the anti-Japanese struggle during the Jiajing period, and was called "since the Japanese trouble, this is the first war achievement." ”

In the thirty-seventh year of Jiajing (1558), the Japanese invaded Dinghai, the residents of the city swore to resist, the Japanese invaded Changle, the city wall collapsed dozens of meters, and thousands of residents lined up to resist the battle, desperately defending. In the same year, the Japanese invaded Yangzhou, and hundreds of merchants from all over the country who came to Yangzhou to do business participated in the battle to defend the city, and the merchant surnamed Gao shot the leader of the Japanese invaders, and Yangzhou City was preserved. Patriotic generals represented by Qi Jiguang emerged in the anti-Japanese struggle, and they relied on the strength of the people to make repeated achievements in the anti-Japanese struggle, and finally won the victory in the anti-Japanese struggle. The Ming Dynasty's nearly 200 years of plague have come to an end.

According to my personal opinion, in addition to valuing China, Japan's invasion during World War II was due to its vast territory and abundant materials, and it may also be due to the centuries-old grievances between the two countries.
