Afterword

At the beginning of 1908, Chen Zhaochang, the director of the Northeast Supervision Office of the Qing government, negotiated with Wu Luzhen and decided to send Bai Wenwei, the second-class staff officer, to Seoul to learn about the situation in Korea. Bai Wenwei, disguised as a businessman, braved the cold and set out from Juzi street. He traveled day and night to Seoul through Huining, Qingjin, xihujin, Yuanshan and Busan in Korea. Because of Japan's invasion, North Korea was divided into two groups of forces. Min Dongho, Minister of the Ministry of war, advocated rejecting Japan. As a result, Li Wanyong, who was obsessed with Japan, gained the upper hand and abolished the king. Japan controlled North Korea. Through his relationship, Bai Wenwei met the son of the Minister of the Ministry of the Republic of Korea, who was a son of Wan. He had a very precious map of dadongyu at home. This map was insignificant in his hands, but it was a piece of hard evidence in the negotiation of the "Jiandao" issue. Because this historical map clearly indicates that Yanji area is Chinese territory. Some people are willing to pay 500 yuan for a dilapidated map, which makes the young master of the Ministry of household overjoyed. Therefore, Bai Wenwei successfully gets the map. It wasn't long before this young man realized that he had made a big mistake. The Japanese police heard about it and reported it to the police level by level. When the Tongjian government learned that someone had bought the dadongyu map, and that it was a Chinese named Bo Wenwei, it was no different from someone throwing a bomb in the Tongjian government. ITO Bowen immediately ordered to trace it and recover the original map at all costs. Although Bai Wenwei's mission to Seoul has been completed, he is in a more and more dangerous situation, so he has to go to the Chinese Consulate in North Korea for a temporary stay. For fear of causing an accident, Consul General Ma Tingliang ordered him to return to China immediately. On the road, Japan's police set up carts everywhere to check pedestrians. A Japanese gendarme stopped Bai Wenwei, holding a note with "Bai Wenwei" in his hand, and asked him, "do you know this man?" Bai Wenwei shakes her head and says she doesn't know. The gendarmerie, worried, searched him again, and found nothing, so they had to let him go. Bai Wenwei arrived in Incheon by car, then went to Yantai by ship and turned back to Mukden. At this time, Bo happened to meet Wu Luzhen who was also in Fengtian, so he reported his trip to Seoul and presented the precious map. This is an important basis for future negotiations.
