How did names like Songjiang spread to Japan?

In the western part of Honshu Island, a Japanese archipelago, there are several places exactly like the eastern part of the Yangtze River Delta in China, namely Songjiang, Kanazawa and Wu. How did the place names in the south of China cross to settle in Japan? This cannot but arouse people's thinking. Songjiang, one of the suburban counties in Shanghai, was named after Songjiang Prefecture, which was built in the 15th year of Yuan Dynasty (1278). As the name of the river, it was seen in the historical records of the Three Kingdoms period as early as the 3rd century A.D., when it was called Wu Songjiang. Qingpu is another suburb of Shanghai. It has a jinze town, named for its fertile soil, dense water network and "land as rich as gold". Known in ancient times as "Baizhuli", it is one of the famous birthplaces of Wu Ge. At the beginning of the Song Dynasty, it became the first residence of Du Nan Prime Minister Lv Yihao who settled in the south of the Yangtze River. Later, his house was called "No.1 Temple", which sounded like a jungle. As for the ancient place name "Wu" in Suzhou, Jiangsu Province, it appeared as early as the 6th century BC, and Shanghai also belonged to the "Three Wu" in ancient times. Songjiang, Ishikawa, Kanazawa in Shimane Prefecture, and Wu in Hiroshima Prefecture, although there are similarities and differences in climate and ecological environment, are all suitable for planting rice, bamboo and fruit, and their names are all later than those of China. Therefore, it will never happen that China place names imitate Japanese place names. The law of place name migration is very common in ancient and modern China and foreign countries, and the phenomenon of place name migration is also common, usually from the mother land to the child land. After Emperor Gaozu Liu Bang made Chang 'an his capital, his father could not adapt to court life and asked to return home. Liu bang built a new city in the suburbs according to the style of his hometown. Residents who moved to Fengpei settled down to do business and were named "Xinfeng". After immigrants from Yorkshire, England, came to the New World, they named it NewYork, or "new york", as a permanent settlement on the east coast to express their attachment to their hometown. Spanish immigrants, on the other hand, extended north and south along the Caribbean coast of America. Out of reverence for the protectors of the motherland, many towns named after Santiago were established. Emperor Yongle, the founder of Ming Dynasty, sent Zheng He, the eunuch of Sanbao, to the Western Ocean to comfort other countries. Everywhere I went, the names of Samoa, Semarang and Lihangpojing appeared. These names came from people's memories of celebrities in various countries. Therefore, there is a causal relationship between the transfer of place names between the mother land and the sub-land. Whether it is coincidence or not, the answer is no, because history has proved that Songjiang, Wu and other places had cultural exchanges with Japan as early as the Tang and Song Dynasties. In heian period in the eighth century, the Japanese had used Chinese characters to form pseudonyms. In Japanese pronunciation, there is also a "five-tone" system. In the first year of Tang Dazhong (847), Japanese Tang Qiufa and monk Ren Yuan returned to China and boarded a ship in Chipu, Dengzhou in early September. This is a Suzhou ship that set sail from Songjiang Port on May 1 1, mainly driven by Silla people. Qinglong Town, Huating County (now Baihe Township, Qingpu County), at the intersection of the Yangtze River estuary and Songjiang estuary, became an important commercial port where seagoing ships frequently docked in the Northern Song Dynasty. "Guangnan, Japan and Silla are one year old or one year old each" (the Ming Dynasty when Longping lost the Lingjian Pagoda) should be a reliable record at that time. In the fourth year of Jiatai (1204), Japanese monks could not abandon Junzhi and came to Huating County (now Songjiang Town), where Songjiang Prefecture was later located, and studied under the "Tiantai" of Guo Chao Tiantai Education College and Goldman Sachs Beifeng Zongyin School. In eight years, the handsome Fan Song returned to China in 13, bringing back more than 2,000 volumes of classics. The Xiannu Temple he founded in Kyoto, Japan still exists today. After shaving, Tuzuozi, Shang emperor and others converted to Buddhism and were named "Daxing Master", which was the ancestor of Shinrikyo in Japan. Facts have proved that the appearance of the same place names in the two countries should have a certain origin, and it cannot be purely a coincidence. The whereabouts of the prisoners of war in the Battle of Hong 'an took place in 10 years before the establishment of the county in Shanghai, that is, the Battle of Hong 'an in the 18th year of the Yuan Dynasty (128 1 year), which was an aggressive war launched by Kublai Khan of Yuan Shizu, with a total cost of140,000 yuan. In this war, 654.38+ 10,000 troops of the South Road came from Qingyuan (now Ningbo), Shanghai, Ganpu and other "boarding ports". According to Zheng De's Records of Songjiang Prefecture, there were 230,000 households in Songjiang before the city was built, and in the twenty-seven years after the war (1290), only160,000 households remained. There are many reasons for the decrease of registered permanent residence, and enlistment is one of them. According to biographies of Haci, Shaquan, Badou in the New Yuan History, the number of young people forced to join the army in Songjiang, Kanazawa and Wu is not 10,000. Even if many people died, drowned and fled back, thousands should be taken alive. At that time, Jiangnan people were famous for their ingenuity, and the advanced cultural skills in Jiangnan were useful to Japan. It is completely reasonable for the shogunate to drive prisoners of war to work and develop in various parts of the country. Perhaps this is the reason why Jiangnan prisoners of war miss their hometown by their names. When the peace envoy went to Japan, the sudden stormy war quickly passed. With the death of Kublai Khan, the tension between the Yuan Dynasty and Japan gradually eased. In the third year of Dade (1299), Yuan Chengzong sent a monk from Putuo Temple, one mountain and one peace, and made heaven with credentials. In the first year of extension (13 14), the "foreign trade ban" was reopened and maritime trade was resumed. Taiding three years (1326), when the Japanese shogunate was in power, he became a monk. He sent envoys to Songjiang Zhen Jing Hospital twice and hired monks to teach Buddhism in Japan. Cheng Zheng applied to join his disciple Du Dong and welcomed him to the Kamakura era the following year. Weiqi Daigo invited his abbots Ren Jian, nanzenji and other famous temples, and founded Kaizen Temple. Cheng Zheng ruled the temple with "Bai Wen Purity", shaved the true Sect of Wu Jia family, promoted Buddhism, and was highly praised by Japanese Asano Nagaakira. He traveled to Japan in 14, and died in Ren Jian Temple, known as "Da Jian Zen Master". His works, such as Collection of Zen Practice and Quotations from a Monk, have a far-reaching influence on the management of Japanese Buddhist temples, Wushan Literature and samurai etiquette. In the next 300 years, the Ming and Qing Dynasties changed, and Zhu Zhiyu (Shun Shui Ren) (1600- 1682), a follower of Amin who was born in Songjiang, traveled across the ocean to preach in Japan. Revered by General Mitsuo Tokugawa and the local people, he was called Mr. Shunshui. He stayed in Japan for 24 years. This is another story in the history of cultural exchange between China and Japan. The tentative solution to the mystery of place names can be summarized as follows: first, the Japanese are amazed at the mountains and rivers in the south of China and named after them; Second, after the Hong 'an War, thousands of prisoners of war in Songjiang and other places did work and develop here. They are named after the place names of their hometown to express their yearning for their homeland. Third, immigrants from southern Jiangsu are named in other ways to educate future generations not to forget Sang Zi's feelings. The above are the assumptions and judgments made by the author based on the similarity of relevant historical materials and the cultures and values of the two peoples, which need more historical facts to confirm. As for thoroughly solving this mystery, historians of the two countries need to learn from each other and explore together. (gold)
