The Tian regime's rule over the central part of Guizhou in Wujiang River Basin can be traced back to the Sui Dynasty, from the second year of Tian Zongxian (582) to the eleventh year of Yongle in Ming Dynasty (14 13), which lasted 83 1 year. In the second year of Emperor Wu of the Han Dynasty (582), Pengshui (central Guizhou) in the lower reaches of Wujiang River included the area in the northeast of Guizhou today, which was located in the "two no matter" land at the junction of Huguang and Sichuan. The mountains are undulating, the terrain is steep, and the traffic is extremely inconvenient. In addition, "Miao Yi has repeatedly rebelled" and the people live in poverty and anxiety. In order to manage the "barbarian land" in central Guizhou, the Sui Dynasty emperors were at a loss. At this time, Minister Su Wei sponsored Tian Zongxian as the secretariat of Guizhou. Tian Zongxian's father and son Tian Weikang (Tian Shikang) have been in office for more than a year and have been in the middle of Guizhou, enjoying political harmony. Emperor Wendi was very happy and appointed Tian Zongxian as our national protector. Later, Ren Zetian, a golden-headed monk sent to Lai 'an Baili, held a peasant uprising, and the court sent Tian Zongxian to war again. After the victory of the Anti-Japanese War, Tian Zongxian was ordered to manage the central Guizhou area, and later he was named Jinlong lord protector, our ambassador to Rong Lu, and his descendants were hereditary. As a result, Tian established the dominant position of central Guizhou, including northeast Guizhou, in the Wujiang River Basin.

In the early years of Emperor Taizong, Tian Weikang, the second emperor, inherited the history of Qianzhou, and was appointed as our ambassador to Qiantan because of his meritorious counter-insurgency. Tian Yang III, a "thief", made meritorious service, and was appointed as the general manager of the Doudufu. The fourth generation Tian can serve foreigners with kindness and accept the military envoys of the rebel army. Through the efforts of more than ten generations, the management of the lower reaches of the Wujiang River has achieved results. However, although the vast areas of Guizhou today are under the jurisdiction of the Zhongtian regime in Guizhou, the sky is high and the emperor is far away, and the people's lives are still poor and restless. It was not until the first year of Daguan in the Song Dynasty (1 107) that Tian Yougong, the 14th minister of Tian Zongxian, joined the imperial court, wishing to be the king's people and founded Sizhou Prefecture. The focus of Tian regime has shifted from Pengshui in central Guizhou to Wuchuan in central Guizhou. According to historical records, the name of Sizhou began in the Tang Dynasty. During the Wude period of the Tang Dynasty, there was a record that Wuchuan was set as a thoroughfare, belonging to Jimi State. Zhenguan years, in the name of Jones Water, changed to Sizhou. According to the Records of Geography of the New Tang Dynasty, Sizhou governs Wuchuan, Wang Si and Jones, and is located in Wuchuan. In the eighth year of Zhenghe (1 1 18), Sizhou was established with its land, leading Wuchuan, Qiongshui and Anyi counties. In the first year of Xuanhe (1 1 19), Tian Yougong contributed to the suppression of ethnic minorities in Guizhou, adding the title of Guizhou's defense envoy (hence the name of Guizhou) and giving it to the Duke of Shao Shi. In the fourth year of Xuanhe (1 122), Wuchuan County was changed into a city, and Qiongshui and Anyi counties were castles, belonging to Guizhou. In the second year of Emperor Gaozong Shaoxing in the Southern Song Dynasty (1 132), Sizhou, Wuchuan, Qiongshui and Anyi counties were restored, which was the former state. So far, eastern Guizhou and northeastern Guizhou have been effectively governed.

After that, no matter whether it is the detention or the rule of thinking about the country, it is the Tian family who knows the country and the Tian family who keeps the country. In the Yuan Dynasty, the central dynasty practiced the chieftain system for the southwest minorities. In the 15th year of Yuan Dynasty (1278), Tian Jinxian of Sizhou attached the land and became a household. Later, it was transferred to the military and political department of Sizhou, which has jurisdiction over Hunan and Guangdong provinces. In the Yuan Dynasty, Tian was subordinate to Tian Maoan, the magistrate of Zhenyuan. Ming Yuzhen, the former leader of the peasant uprising, founded Yuan Shuaifu of Sinan Road to appease and rule the capital, and Sizhou was divided into two. In the twenty-fifth year of Yuan Shundi (1365), Yuan Sinan joined Tian Renzhi, Zhu Yuanzhang still set Sinan as the propaganda department, and Tian Renzhi was still the propaganda ambassador; Zhu Yuanzhang changed the ambassador of Sizhou to the propaganda department of Sinan Town West, and took Tian Renhou as the propaganda ambassador. Jurisdiction over Wuchuan County, Zhenyuan Prefecture, Fourteen States and Fifty-two Long lawsuits. From today's geographical point of view, its region "starts from Yongshun and Baojing in Hunan in the east, reaches Wuchuan, Fenggang and Shibing in Guizhou in the west, reaches Youyang in Sichuan in the north, and reaches Libo and Congjiang in southern Guizhou in the south, occupying almost two-thirds of Guizhou and a part of western Hunan, and its territory is far wider than that of Sizhou in the Tang and Song Dynasties (1)". The Yuan Dynasty was the largest chieftain with the widest jurisdiction and the highest level in the Tianfang regime in Sizhou. No wonder Zhu Yuanzhang said in the early Ming Dynasty that "Guangdong and Guangxi are too close to the Yellow River to broadcast Tianyang", that is, Sizhou Tian and Bozhou (now Zunyi) Yang were powerful. In the Yuan Dynasty, the emissary of Sizhou was divided into the emissary of Sinan and the secretary of Sizhou government, so the Annals of Guizhou in the Republic of China said: Sizhou "was named Sizhou since the secretary of Xuanqingjiang County in Tu Ping, Longquan, so it was renamed Sinan". It can be seen that from the Yuan Dynasty to the first year (1264 ~ 1294), Sizhou Tian regime was divided into two parts, some of which have moved to Sinan. In the Ming Dynasty, Sinan Xuanwei Division had jurisdiction over Shuidejiang, Yiman, Youxi along the river, Si yin river, langxi, Zhenyuan Creek Cave, Jin Rong Jinda, Shibing, Pianqiao, Qiongshui Cave (the five long lawsuits of Tuanle, Demin, Xiao Ai, Beidai and Qiongshui), Fangzhen Cave, Tongren, Provincial Creek, Tixi and Qiongshui. It is equivalent to today's counties such as Cengong, Yuping, Shiqian, Fenggang, Liping, Jinping, Congjiang, Rongjiang, Dejiang, Yanhe, Yinjiang, Shibing, Sansui, Zhenyuan, Tongren, Jiangkou, Wanshan and Songtao, as well as some places in Youyang, Chongqing. These places are adjacent to Sichuan and Huguang and are at the crossroads. Since the Yuan Dynasty, they have been passing through the trunk line from Huguang to Yunnan, and there are land and water passages leading to Sichuan and Huguang, which is also one of the passages for Sichuan salt to enter Guizhou. Sichuan, Shaanxi, Huguang and Jiangxi are the most popular places with relatively developed economies and important political and military strategic values.

At this point, Sinan and Shi Tian Xuanwei in Sizhou are two of the four major toast in Guizhou. Sinan and Sizhou (now Cengong) became the political, economic and cultural centers of northeast and east Guizhou, respectively, and they were also the direct places for land conversion under their jurisdiction, which also laid a geographical foundation for Guizhou to build a province.

From the Warring States to the Han Dynasty and then to the Zhou Dynasty, Tian Tusi was a prominent family in the land of central Guizhou or Sizhou.

According to the Taiping Magnolia, "When Fuling was a barbarian, there were Ran Shi, He Shi and Shi Tian. This settlement is the most prosperous, with thousands of households and thousands of households ... In the seventeenth year of Taihe (493), Shuai Tian led 4,000 households. " It's really not easy to have 4,000 people in central Guizhou. The land is vast and the population is sparse. It can be seen that Tian is a famous family with a large territory.

In the fourth year of Baoding in the Northern Zhou Dynasty (564), Tian Sihe, a beautiful man in Fuling, was attached to the ground, and in the third year of Jiande (574), Fengzhou was changed to Qianzhou. "

"County Records along the River" contains: "In the second year of Emperor Wendi (582), Tian Zongxian was the secretariat of central Guizhou."

According to Tian's genealogy quoted in the County Records along the River in the Republic of China, "In 582, Emperor Wendi opened the emperor for two years, and there were repeated rebellions in central Guizhou. Minister Su Weibao played (Tian) as the secretariat of central Guizhou, and his son Wei Kang was in office for more than a year, and he ruled in central Guizhou, where Emperor Wendi was appointed as the official of lord protector. An Baili, a rebel in Swan Mountain, Shaanxi Province, sent a golden-headed monk for chaos, dispatched troops to fight thieves in Swan Mountain, and the thieves were defeated by Sichuan and Cheng. Zong Xian pursued it, but the thief lost again. He went to Chaotianmen in Chongqing, dived into the river, chased him and beat him, and the thief lost again. Soldiers are painting, visiting thieves and asking people where to go. People answered them with stone horses, which means Zhou Yong. Zong Xian looked at the terrain in detail, surrounded by mountains and water, and lived in seclusion. The beheaded thief was ordered to be in charge of 18 castles and 48 crossings on the border in Sizhou, central Guizhou. Xuan Jiafeng was appointed as Jinlong lord protector, the ambassador of Rong Lu Province, and future generations inherited the post of comforting the spirit, and the military and the people jointly managed it. "

According to historical records such as History of Yuan Dynasty, History of Ming Dynasty, Annals of Guizhou, Annals of Sizhou, Annals of Sinan, Annals of Zhenyuan, Annals of Yanhe County, Annals of tongren city, Annals of Cengong County and Annals of Tianyanmentang:

In the 25th year of Yuan Dynasty (1July 27th, 365), on the seventh day of July, the military and civilian envoy of Sizhou and the secretariat of Huguang were granted Zuo Chengwu's power to quell the chaos, and the fierce doctor was added to take charge of 80,000 civil servants in Guzhou, Tian Renhou, and Zhang Siquan, who was in charge of everything, was sent to 34 states (long-term litigation) in/kloc-0 county.
