Emperor Wanli of the Ming Dynasty conferred Toyotomi Hideyoshi as the Japanese king.

1June, 593, Japan was unable to deliver materials due to naval defeat. In addition, due to the excessive destruction of North Korea and the prevalence of plague, it is not easy for local people to collect food, and they are eager to preserve the achievements of occupying the Fourth Route in South Korea. So they sent envoys to accompany Shen Weijing, the special envoy of the Ming Dynasty, from Busan to Beijing for peace talks. In July, the imperial court announced that it had withdrawn its troops to pay tribute to Japan, so Li Jun retreated, leaving only 7,600 people with guerrilla Wu Weizhong to guard the key points respectively. However, Shi Xing, the minister of the Ministry of War, decided to advocate peace, so he withdrew Wu Weizhong's soldiers. As a result, only Liu Ge's soldiers stayed to defend. In September, although Li Yong, the king of Korea, thanked the imperial court for its rescue and help to restore the country, he was secretly dissatisfied with tomorrow's peace talks and ruled out North Korea. At this time, the Japanese army still occupied the fourth road in the south of Korea and firmly held Busan City. In February, 65438, the Ming Dynasty ordered Governor Ji Liao to take care of North Korea and recalled Song Yingchang and Li. Zongshen ordered the soldiers to withdraw as much as possible, but at the same time stressed that although the troops were withdrawn, "the situation of the Japanese is very cunning, and it is impossible to say that things are over."

1593 (21st year of Wanli) On May 8th, Toyotomi Hideyoshi met with the delegation of Ming Dynasty who arrived in Japan in Nagoya. Due to the language barrier, the talks between the two sides are still held between Shen Weijing and Konishi Yukinaga. Toyotomi Hideyoshi put forward seven "Daming and Japanese peace conditions":

First, welcome Princess Ming Di to become the Japanese emperor; Second, develop the surveying industry; Third, tomorrow, the military attaché s of the two countries will swear an alliance forever; Fourth, the capital and the fourth road were returned to North Korea, and the other four roads were ceded to Japan; 5. North Korea sent a prince to Japan as a hostage; 6. Return the captured Korean Prince II and other North Korean officials; 7. North Korean ministers will never betray Japan. Shen Weijing agreed to the seven suggestions, but lied to his peers, such as Xie Yongren and Xu, that he had agreed to submit to the Ming Dynasty, asked for tribute, and withdrew from the Japanese invaders. On the other hand, Konishi Yukinaga reported to Toyotomi Hideyoshi that the envoys of the Ming Dynasty had agreed to Toyotomi Hideyoshi's seven suggestions, and only needed to send Japanese envoys and Ming envoys to Beijing to ask Ming Chengzu for final approval. In this way, through the mediation of two negotiators, the two sides almost reached an "agreement." 1594 10, Japanese peace envoy Xiao Xi Ruan went to Beijing with the Ming delegation, and Xiao Xi Ruan had already reached an offensive and defensive alliance with Konishi Yukinaga.

Xiao Xi Ru 'an arrived in Beijing to negotiate with Shi Xing and agreed to three conditions put forward by Shi Xing:

First, the Japanese army quickly withdrew from North Korea and Malaysia after being blocked; Second, only conferring titles without paying tribute; Third, it is sacrosanct to mend fences with North Korea. At that time, the Ministry of War also had a detailed conversation with Xiao Xiru, a Ming man who cheated him and didn't understand Japanese. At this time, Shen Weijing also submitted a forged Japanese watch. The monarchs and ministers of the Ming Dynasty were very satisfied. Ming Shenzong immediately canonized Toyotomi Hideyoshi as king of Japan and canonized Japanese ministers according to the list provided by Xiaoxi.

Later, in 1595+0, 1 year, the Ming Dynasty sent a special envoy to make Toyotomi Hideyoshi king of Japan, so that Shen Weijing could go with him. The content of the imperial edict is as follows: "Serve the heaven and carry the emperor, and it is said that the sage will be blessed with great fortune. If the heaven overtakes, the emperor's life must be respected. The sunrise in the corner of Pujiang and the sea will not be given. In the past, my ancestors were born in many ways. Turtles, dragons, and chapters give far-reaching fusang territory; Zhenmin Dazhuan is the mountain of Rongshi Town. Heirs are raised by Haibo and occasionally separated. In our heyday, Zier Toyotomi Hideyoshi, a rising maritime country, was called China. Xi Chi's humble envoy is eager to go with him. Knock on the pass of North Wan Li, and wish to get married. Love is based on respect, and goodness is based on softness. I hereby make you king of Japan and grant him the authorization of the empire. In the play, the dragon is full of imperial edicts, the crown is on the sea, the fancy clothes are popular, and the vassal guards are in China. It is time to repair the official position. But follow the main beam and be grateful for the gratitude of the emperor. Sincerity is irreplaceable. As long as you believe in what you say, you will always respect your voice. Chin! "

This imperial edict, now in the Osaka Museum, was written in the usual imperial style, just like the tone of the emperor of a big central country's favor to a small country. According to some historical records, Toyotomi Hideyoshi flew into a rage and said, "I control Japan, I want to be king, why not be king!" " Throwing the imperial edict on the ground angered the envoys and soon sent troops to invade North Korea. But another way of saying it is that Toyotomi Hideyoshi, though reluctant, accepted the knighthood of the Ming government on the surface, even annoyed with the words "Wan Li knocks on the door and implores the attachment" in the imperial edict of Emperor Zongshen, but he can only submit to humiliation and accept it. The next day, he also "dressed in the crown of the Ming Dynasty, hosted a banquet in Osaka for the envoys of the Ming Dynasty". But in fact, it has long been accumulating strength and brewing another attack on North Korea. Shi Xing and Shen Weijing, who were in charge of negotiations with Japan at that time, went their own way and deceived others, trying to hide Toyotomi Hideyoshi's true intentions from Emperor Wanli in an attempt to muddle through. Then Toyotomi Hideyoshi will punish Konishi Yukinaga and expel the China and South Korean missions. This lasted for two years and completely collapsed. On the way home, Shen Weijing stayed in North Korea and was afraid to go back to Beijing. He forged a thank-you note from Toyotomi Hideyoshi, which was submitted to the court by another special envoy. This fake form of gratitude was discovered by the Ming court, and the news that Japan was preparing for war again came from North Korea. Ming Shenzong was very angry when he knew that he had been cheated. He immediately ordered Xing Jun to imprison Shi Xing, the minister of the Ministry of War, and ordered the Ming garrison to seize Shen Weijing and execute him on the spot.
