Tokyo City is located in Ning 'an City, Mudanjiang City, Heilongjiang Province. Tokyo City is the old city of Beijing (Longquan House), also known as "Huhan City", and was called "Tokyo City" in Qing Dynasty. Located in the southeast of Heilongjiang Province, on the east bank of Mudanjiang, in Bohai Town (formerly Tokyo Town) of Ning 'an City, it is the site of the capital of Bohai Kingdom, commonly known as "the site of Longquan House in Beijing". In 755 AD (the 14th year of Tang Tianbao), King Qin Mao of Bohai moved his capital to Longquan House in Shangjing. In 785 (the first year of Tang Zhenyuan), he moved to Tokyo Longyuanfu. In 794 (the tenth year of Tang Zhenyuan), Wang Hua-Zhuo became a "national rejuvenation", and moved his capital back to Longquan House in Shangjing until the end of the country, where he served as the capital for more than 161 years. Basic introduction Chinese name: Tokyo City Location: Ning 'an City, Mudanjiang City, Heilongjiang Province Covers an area of? 4.2 square kilometers, also known as "Huhan City" Country: China City: Mudanjiang City, Heilongjiang Province Tokyo City is located in the Tokyo City Basin, surrounded by mountains on all sides and surrounded by water on three sides. "The distant mountains are the screen, and the water is near, and the mountains and rivers are dangerous and solid." The old city of Shangjing is large-scale, consisting of outer city (profile city), inner city (imperial city) and Miyagi (Forbidden City). It is a big city designed and built after the Chang 'an model in Tang Dou, and the existing city is basically complete. Miyagi, inner city and outer city are surrounded by layers. The north wall of the outer city is 4946 meters long, the south wall is 4584 meters long, the west wall is 3511 meters long, and the east wall is 3359 meters long, covering an area of more than 16 square kilometers. The inner city is built in the north of the outer city, which is rectangular, about 1152 meters from east to west and 471 meters from north to south. It has walls in the south, east and west, and the north is connected with Miyagi. The wall is made of stone, and the residual parts of the east and west walls are about 1 meters high; The south wall has been turned into cultivated land. Miyagi is in the middle of the inner city, rectangular, about 721 meters from north to south, about 621 meters from east to west, with a circumference of 2681 meters. It has a stone wall with an average height of 3-4 meters. In Miyagi, there are five temple sites arranged from south to north on an axis, and most of the foundation stones are still well preserved. There is an imperial garden on the east side of Miyagi, with ponds, pavilions and rockeries. The old city of Diaoshuilou Waterfall in Tokyo is one of the great capitals of China in the Middle Ages, but there is no specific written record of its construction date and situation. According to textual research, it may have been built in the first half of the 8th century. In 926 AD (the first year of Tian Xian, the first emperor of Qidan), Qidan destroyed the Bohai Sea, established Dongdan State, and changed the "Huhan City" into "Tianfu City" to become the capital of Dongdan State. In 929 (the fourth year of Tianxian), Dongdan moved south and the capital was destroyed. Since then, the old city of Shangjing has been lost for hundreds of years, and it was not until the historical records in the early Qing Dynasty that it was recorded that "there is an ancient city here, and the natives said that Tokyo ...", hence the name "Tokyo City", also known as "Tokyo Tun". This has attracted the attention of academic circles at home and abroad, and has been investigated, verified and excavated many times. In March, 1961, the State Council was approved and announced as the first batch of national key cultural relics protection units. In the most prosperous period of the Tang Dynasty, a powerful Bohai Kingdom appeared in the northeast, including the present northeast and the south of Xing 'an Mountains outside Russia. * * * There are five capitals: Tokyo Longyuan House, Xijing Yalu House, Nanjing Nanhai House, Zhongjing Xiande House and Shangjing Longquan House. In 755, Bohai moved its capital from Xiande House in Beijing to Longquan House in Shangjing, which is now Bohai Town in Ning 'an City, Heilongjiang Province. Longquan House, the capital of Bohai State, was a famous metropolis at that time. The capital was completely built in accordance with Chang 'an City, consisting of outer city, inner city and Miyagi City, with an area of about 16 square kilometers, which is one fifth of Chang 'an City. Judging from the existing sites, the northern half of the inner city consists of five palaces, where the rulers work and live, while the outer city consists of imperial gardens, lakes and pavilions. There is an eight-treasure glazed well that draws water, and it can still make clear sweet water. On the night of February 23, 926, Yelu Abaoji, a Khitan, led the iron cavalry to cross Changbai Mountain in two ways, and after six days and six nights of galloping, they arrived in Shangjing and surrounded the capital. The city of Beijing was besieged for three days, and the Bohai people had no choice but to break through. The king of Bohai was forced to wear mourning clothes, raise Su Zan, and surrender in front of Bao Ji Ma. On March 5, Bao Ji sent nearly 13 people, including Kang Moheng, to the city to ask for weapons, but they were killed by angry Bohai soldiers. Bao Ji was furious, attacked the city from east, west and south, and went to Beijing to fall. The Bohai Kingdom, which lasted for more than 211 years, was destroyed, and the whole territory was incorporated into the territory of the Khitans. Dongdan State was established in the original Bohai Sea, and Shangcheng was renamed as "Tianfu City" and became the capital of Dongdan State. Three years later, the people of Qidan, who built their capital on other people's land, were suspicious and uneasy, and always felt that there was a strong rebellion in this capital. The Khitans decided to move their capital to Dongping County (now Liaoyang City, Liaoning Province), forcing the Bohai people to move with them. In order to make the Bohai people completely cut off the idea of returning home and revenge, the Qidan people decided to burn the capital city, and "the imperial palace and the princes' mansion were all reduced to hazel rubble." The fire burned for more than half a month, and the civilization of Bohai for more than 211 years was completely destroyed by fire. According to the Records of Liao History and Geography, there are more than 9,411 adherents of Bohai Sea who moved to Liaodong and other places this time, and most of the 113 cities obtained after Qidan destroyed Bohai Sea were abandoned in this migration. Haidong Shengguo only left "a deserted city versus a blue stream", while the literature and history materials, articles and classics of Bohai were also burned, leaving only the ruins of palaces, castles and tombs, leaving rubble, arrows and iron covered with red rust. Prosperous and prosperous, it returned to the wild and wild overnight. The prosperous capital disappeared, and the Bohai Kingdom was forgotten. This land became a cold and desolate no-man's land. Until the Qing dynasty, it was uninhabited for 711 years. By the time of Qing Dynasty, Bohai Kingdom had already disappeared into the dust, and Ningguta (now Ning 'an City, Heilongjiang Province), which was only 21 miles away from here, became a hell on earth for exiled dismissed officials and literati in Daxing Literary Prison, and a large number of Jiangnan intellectuals were exiled to Ningguta. This group of scholars from the Central Plains who lived on the edge of the snowy area finally discovered the ruins of this deserted city. Among them are Fang Gonggan and Wu Zhaoqian, gifted scholars in the south of the Yangtze River. In the 14th year of Shunzhi (A.D. 1657), they were sentenced to stay in Ninggu Pagoda because of the imperial examination case, and wrote A Brief Account of the Unique Region and Records of Ninggu Pagoda. In these works, an incredibly huge ruin is mentioned, but these learned talents can't tell clearly what era this city is. In 1961, the capital site of Bohai State was listed as the first batch of key cultural relics protection units in China by the State Council. Today, the visible sites include the Longquan House site in Shangjing, the ancient well site, the forbidden garden site, the street altar site, the temple site, the ancient tomb, the ancient bridge site, Xinglong Temple, etc. The main relics include the stone lamp building, the big stone Buddha, the relic letter, the big stone turtle, and the writing tile. Now the local authorities are trying to declare the Bohai site as a world cultural heritage. Attending Beijing is the first of the five capitals in Bohai. It is modeled after Chang 'an in Tang Dynasty, and covers an area of 16 square kilometers, including outer city, inner city and Miyagi. The outer city is earthen wall, the inner city is stone wall, and Miyagi is basalt wall. Five halls connected by cloisters are arranged on the north-south axis. In 926, the Liao State destroyed the Bohai Sea and established Dongdan State. In 929, Dongdan State moved south to Liaoyang, and Longquan House was destroyed. Its site has become a national key cultural relic protection unit since 1961. There is a Xinglong Temple in the ruins of the ancient city, which was built on the site of Bohai Temple in the Tang Dynasty in the Qing Dynasty. There are Buddhist stone carvings in the temple, such as the falling of a stone lamp, the falling of a turtle and the big stone Buddha. There are also some tombs, kilns, bridges and other sites in the area around the ruins of the ancient city. Tokyo Town is a thousand-year-old city with a long history, and it is one of the birthplaces of Manchu. More than 3111 years ago, there were human activities here. The Dongkang site excavated here is one of the important primitive social sites in Mudanjiang Valley, and its history can be traced back to the early Iron Age (Han and Jin Dynasties in China history). In Shang and Zhou Dynasties, it was the hometown of Sushen people, and in Tang Dynasty it was under the jurisdiction of Huhan City (the capital of Bohai Sea). To the Republic of China, it was still overgrown with weeds and deserted, only that there were several families in the home and the sugar shop, commonly known as Dongdawazi. In 1932, the Japanese invaders occupied this place, and the following day, when the Tuning (now Mu Tu) Railway was falsely built, Tokyo City Station was set up in Xinliping, which is eight miles away from Tokyo City. Then a timber yard and an airport were built near the railway station. At that time, it was under the jurisdiction of Tokyo City Office (now Bohai Town), commonly known as Eight Streets. In 1936, in order to strengthen the rule of China people, the Japanese invaders launched a large-scale activity of returning to their hometowns and merging villages. At that time, group tribes were established in Guzhuang, Dongkangzhuang and near the railway station. Therefore, the population of Tokyo City increased sharply, which also laid the pattern of Tokyo towns.
