The green line should not be where is the heavens? Where is the earth? Where is the Central Plains

I remember my teacher saying that there is only one question mark when it comes to selective interrogative sentences, and I'm not sure.

What are you asking, the green line is exactly what you said.

Nine borders - nine border towns in Liaodong, Jizhou, Xuanfu, Taiyuan, Datong, Yansui (Yulin), Guyuan, Ningxia and Gansu. After the establishment of the Ming Dynasty, the Northern Yuan, who fled to the northern frontier, still harassed from time to time, seriously threatening the rule of the Ming Dynasty. In order to consolidate the northern frontier, Zhu Yuanzhang, the Taizu of the Ming Dynasty, repeatedly sent generals to the north, and at the same time, he also divided his sons Zhu Di and Zhu Quan to garrison the northern frontier.

Ming Chengzu Zhu Di went out of Mobei five times, and set up towns along the border and sent troops to garrison. At the beginning, four towns of Liaodong, Xuanfu, Datong and Yansui were set up, followed by three towns of Ningxia, Gansu and Jizhou, and two towns of Shanxi and Guyuan, which were nine sides. It's not nine levels.

The above answer is basically correct.

Nine Sides were nine important towns on the northern border of the Ming Dynasty. Because Taizu Zhu Yuanzhang realized when he founded the country that the main threat of the Ming Dynasty to the outside world was Mongolia in the north. So the northern border was divided into nine defense zones.

As long as the stability of these nine defense areas is ensured, the external troubles of the Ming Dynasty will basically be worry-free.

At the end of the Ming Dynasty, due to the rise of the Northeast Houjin. The four defense areas of Liaodong, Jizhou, Xuanfu and Datong, which are located in the northeast and north, have received further attention and are divided into two major defense areas, Xuanda and Jiliao. There were two governors each with direct control over military affairs.

There is another idiom about the "nine sides", that is, "brave champion three armies, filial piety to the nine sides", which is about Wu Sangui. The nine sides here also refer to the nine defense zones.

From the beginning of the Ming Dynasty to the middle of the Ming Dynasty, the Ming Dynasty successively set up nine important towns to dominate the front.

Line sergeant, these nine important towns are collectively referred to as Jiubian Town, namely: Liaodong Town (Zhiguangning, now Liaoning North Town), Jizhou Town (Zhisantun Camp.

Northwest of Qianxi County, Hebei Province), Xuanfu Town (Xuanfu, now Xuanhua, Hebei), Datong Town (located in Datong, Shanxi), Mountain.

Xizhen (located in present-day Ningwu, Shanxi), Yansui Town (located in present-day Yulin, Shaanxi), Ningxia Town (governed in present-day Yinchuan), and Guyuan.

The town (located in present-day Guyuan, Ningxia) and the town of Gansu (located in present-day Zhangye, Gansu). Each town has a chief military officer, a governor, and several towns.

There is also the Governor. The number of troops commanded by these feudal officials sometimes reached one million, and sometimes there were hundreds of thousands, accounting for about the country's military strength.

two-thirds.

The first nine sides refer to an event nine sides: the nine important military towns in the northern border of the Ming Dynasty (the four towns of Liaodong, Xuanfu, Datong and Yansui were initially established, followed by the three towns of Ningxia, Gansu and Jizhou, and the two towns of Shanxi and Guyuan, which were nine sides).

In the first year of the Apocalypse (1621), Jin broke Shenyang, and Yuan Yingtai died; Soon Liaoyang fell again, shaking the Beijing Division. Xiong Tingbi was summoned to the court, and the first tripartite arrangement strategy was built: in Guangning (now Beizhen, Liaoning), Houji Bu rode to contain the main force of Houjin; In Tianjin, Deng, Lai (now Penglai, Ye County, Shandong) each set up a governor, set up a boat division, and took the opportunity to enter southern Liaoning; Set up a strategy in Shanhaiguan to control the three parties.

Then he entered the military department and the right deputy capital of the imperial history, stationed in Shanhaiguan, and resumed the military affairs of Liaodong. At the same time, the imperial court promoted the king to the governor. The two of them are the main battle, the other is the main defense, and the opinions are not in harmony.

Wang Huazhen supported heavy troops to defend Guangning, while Tingbi had a few thousand soldiers in vain. Hua Zhen held heavy troops, did not listen to moderation, and launched an attack with the enemy as an internal response, which was self-defeating, and abandoned Quang Ninh and retreated after the defeat. Tingbi's strategy was difficult to realize, and seeing that the general trend had gone, he retreated to Guannai and was imprisoned and killed.

Wei Zhongxian instructed the eunuch party to protect Wang Huazhen, and entrusted the crime to Tingbi, Tingbi was killed, and the corpses were sent to the nine border towns to show the public (Chuanshou Jiubian). Xiong Tingbi was courageous, knew the military affairs, and was good at shooting, and was a prominent military commander in the late Ming Dynasty. Chongzhen won Zhaoxue and was ashamed.

There is "Xiong Xiangshu Public Collection".

As early as the end of the Ming Dynasty and the beginning of the Qing Dynasty, the remaining Mongolian tarts were frightened by the Eight Banners Army of the Later Jin, and later they were dismantled, and they were seriously damaged in the Ming and Qing wars at that time, and many Mongolians were requisitioned into the army, and they could not organize troops to enter the pass and loot at all.

However, during the Qing Dynasty, although the Han people in the border passes did not suffer from plunder, but in the Qing Dynasty, the Han people were untouchables, and they were oppressed and treated very unfairly.

The Han people living in the border areas will inevitably have conflicts with the Mongols, and the Manchu rulers advocated the integration of Manchu and Mongolia, so this answers your first question, the Mongols no longer invaded the nine borders like the Ming Dynasty, because in fact, Inner and Outer Mongolia were under the rule of the Manchus. And because of the unity of Manchu and Mongolia, in the conflict between the Han and the Mongols, the Manchu rulers must have been more biased towards the Mongols, so they were worse than the Ming Dynasty.
