A.D. 1649 is the sixth year of Shunzhi of the Manchu Qing Dynasty, and it is also the fifth year of Longwu of the Southern Ming Dynasty.

Military defeat is the most direct inducement, and another time and space in the smooth Qing Empire, the Manchu Qing in this time and space fought too many defeats, which triggered a series of vicious circles, in addition to the military aspects of passivity, political, economic and social aspects are dragged down by it, and problems continue to appear, which consumed a lot of manpower, material and financial resources of the Manchu Qing Dynasty, and in turn pulled the military hind legs, especially after the Battle of Ningzhen, the national strength of the Manchu Qing Dynasty showed a downward trend, unlike the vigorous founding dynasty, It's like an old empire that is riddled with scabies.

In addition to the internal problems, the external environment of the Manchu Qing Dynasty also began to deteriorate, and although the problems were not very big for the time being, there were already signs of bad things.

Two months after the Battle of Nyongjin, an earthquake occurred in the political situation in Korea, and the anti-Qing "Mountain Party" overthrew the pro-Qing "Han Party" and came to power.

The Manchu Qing Dynasty arose between the white mountains and black waters, because most of Siberia in the north was a barren and uninhabited land (Russia also invaded Siberia in the late seventeenth century, and fought a war with Kangxi, and the two sides finally signed the "Treaty of Nebuchu"), there are only three and a half powerful neighbors around, the first one is of course the Ming Dynasty in the south, the second is Mongolia in the west, the third is North Korea in the east, and the remaining half is the island country of Japan, because across the sea, the Manchus and the other side do not have much intersection, so they can only be regarded as half neighbors...... Of these three and a half neighbors. Although North Korea is at the back, it is only separated from the Manchu Qing Dynasty's "Land of Longxing" by the Yalu River. It is very important.

Between Korea and the Manchus, centuries of grievances and grievances were entangled.

"South and North Kou". It has always been the biggest external trouble in North Korea, when the Jurchens rose in the Northern Song Dynasty, the Jin State once forced Korea to submit to become a subject state, but the Jin State was short-lived and was soon replaced by the Mongols, after the fall of the Mongol Yuan, the Goryeo Dynasty was also overthrown by the Joseon Dynasty of Li Sung-gye, and the Jurchens at that time were forced to submit to them, and the Koreans had the upper hand. At the end of the Ming Dynasty. The Joseon dynasty also declined, but the Manchus rose to prominence and invaded Korea in 1636, when the Joseon king Injo was forced to surrender and became a vassal state of the Manchus...... In June 1649, Renjo died, and Xiaozong Li Hao succeeded to the throne, and began to suppress the pro-Qing "Han Party" official Jin Zidian and others, and reused and promoted the anti-Qing "Mountain Party" official Song Shilie and others.

"Hu people have no luck for a hundred years!" Since Xiaozong Li Hao below. At that time, Korea was deeply influenced by Confucian culture, and regarded the Manchu Qing Dynasty as a dog and a sheep Yidi, in addition to the official documents and congratulatory tables to the Qing Dynasty, a qiē internal official documents. Including the royal tombs, the temple, the temple of literature to enjoy the blessings, still use the Chongzhen year name. Li Hao and Song Shilie also had high hopes for the anti-Qing forces such as the Southern Ming Dynasty, and after the news of the Battle of Ningzhen came. With his support, the "Mountain Party" overthrew the "Han Party" that controlled the government in one fell swoop and regained power. Li Hao began to actively reorganize the armament for war, intending to "take it by surprise." Directly outside the customs, the Central Plains righteous heroes, there is no responder! The national strength of North Korea is weak, and the Imperial Forest Army in the area of Seoul is only 7,000 people, Li Hao increased taxes, actively expanded the army, and expanded the Royal Forest Army to 20,000 in just two months, preparing to launch a Korean version of the Northern Expedition.

At the same time, he was also actively looking for allies, sending envoys to the south by boat, liaising with the Longwu court of the Southern Ming Dynasty to jointly resist the Qing Dynasty, and contacting Japan to ask it to send troops to attack the Qing Dynasty. When Li Hao was actively preparing, he suddenly received news that Zhu Cihuan, the son of Chongzhen Emperor, was alive, and the Nanming regime was split.

This qiē could not be completely concealed from the eyes and ears of the Manchus, Korea was a subject state of the Manchu Qing, but it still maintained relative independence, if the trouble was not too excessive, the Manchus were not willing to mobilize troops to attack Korea, and Dolgon was seriously ill, so he endured this breath for the time being, but issued an edict demanding that North Korea remove Song Shilie from his official post and send Jin Zidian and other pro-Qing "Han Party" leaders to Beijing.

It was not only North Korea but also Mongolia that gave Dolgon a headache.

The Mongols at the end of the Ming Dynasty and the beginning of the Qing Dynasty have long lost the glory of the Yuan Empire, and the grassland was divided into various tribes of all sizes, and generally submitted to the Manchu Dynasty, but there are also many disobedient tribes who will rebel at every turn.

At this time, the Mongolian tribes were basically working independently, and their own people often fought with each other, and they were not even loose alliances. Since the Mongols were incapable of managing themselves, and the Manchus did not have the energy to be nannies, they supported and co-opted some pro-Qing Mongol tribes, and the other tribes were left to fend for themselves...... Unexpectedly, as the Qing army was constantly defeated by the Ming army, these Mongolian tribes also became emboldened, launched provocations and looting against the pro-Qing Mongolian tribes, and even ran to Tongliao and Chifeng, posing a threat to the foundation of the Manchu Qing Dynasty.

This crooked wind must be suppressed! If they are defeated, Mongolia will fall into long-term chaos, and the Manchus will no longer have a safe barrier, so should the dignified Qing Empire be like the Ming Dynasty, supporting a huge nine-sided army to ensure the security of the north? It stands to reason that the Qing court should immediately send troops to conscript the rebellious tribes, but Dorgon really had no troops to send.

After thinking about it, he could only transfer troops from Shanxi, and Dolgon was forced to transfer more than 10,000 Qing troops to fight in the Mongolian steppe. The winter in Inner Mongolia was extremely cold, but fortunately, the Eight Banners were never afraid of the cold, and with the cooperation of the pro-Qing tribes, they fought a fierce battle with the anti-Qing tribes and defeated them all...... The good news came, but Dolgon was not happy, because he got a news at the same time, taking advantage of the opportunity of the Qing army to divide troops to attack Mongolia, part of the Ming army in Datong City took the opportunity to break through, and some Ming troops in the city continued to hold on, and Jiang Jiu's own whereabouts are unknown.

Of the three and a half neighbors of the Manchu Qing Dynasty, three of them are looking for trouble for them, and the other half is also not at ease, Japan's attitude has also changed recently, and the Manchu Qing Dynasty has almost cut off trade contacts, but Zheng Chenggong is very close, openly and secretly supporting the anti-Qing forces, coupled with the continuous harassment of Shaanxi by various ethnic groups in the northwest, the Qing Empire has just been established, and it is in dire internal and external troubles.
