During this period, the Nguyen dynasty of Vietnam entered a period of complete decline. Pen % fun % Pavilion www.biquge.info

In the whole dynasty, there was almost no industry, and the only industry that could be regarded as mining and iron casting was money, but all of them were controlled by the Ministry of Industry of the Imperial City of Hue. In other handicrafts, due to the imperial court's artisan collection system and the oppression of exorbitant taxes and miscellaneous taxes, the handicraft industry was completely deserted, and the craftsmen gradually changed careers, preferring to act as tenants and vagrants. On the business side, there are serious drawbacks. The system of emphasizing agriculture and suppressing commerce has seriously restricted the development of commerce, and many goods transactions have been banned.

In addition, the two forces of Zhu Hongying and Liu Changqing in northern Vietnam have recently made a great disturbance, and the entire area of northern Vietnam, all the way to Hanoi, and the surrounding areas have been forbidden to buy sulfur saltpeter, etc., and even the markets around Hanoi have been closed to the public, and the roads for trade have been controlled by officials and lords in various places, and the toll money has been levied heavily. As a result, the entire area of northern Vietnam is completely like a pool of stagnant water.

The central and southern regions of the Imperial City of Hue were strengthened by the Nguyen Dynasty's control, which not only controlled the internal flow of goods, but also controlled foreign trade. Imports were limited to pig iron, lead and sulfur, which were needed by the Nguyen dynasty, and exports were strictly controlled, and the sale of silk and rice to foreigners was strictly prohibited. Even the local taxes were not paid in silver, but were replaced by ginseng, cinnamon, lychee, longan and other physical items needed by the Nguyen royal family and officials in the court instead of currency, which severely restricted the circulation of money.

In terms of agriculture, Vietnam was already Vietnam's strong point, but due to the rule of the Ly and Nguyen dynasties, farming techniques were backward, and the farming tools and techniques of the Ming Dynasty were still used. Not only that, but the people's private fields were exploited by the officials and landlords, and all fertile fields were encroached upon by the landlords, and the peasants who lost their land left their homes and became displaced people.

In this way, many displaced people rushed to the north of Vietnam and joined the forces of Zhu Hongying and Liu Changqing, so the power of the two is getting bigger and bigger, and there is already a faint momentum of fighting against the Nguyen dynasty.

But for some reason, Guangxi and other places in the north have not moved, and the crusading army there did not send troops to attack the two.

At this time, Zhu Hongying and Liu Changqing finally fought for territory, more and more friction began to appear, and between the two, because after more than a year of development, their conscious power increased greatly, and they began to attack each other before they occupied Hanoi. After several clashes, both sides lost thousands of men, but found that neither could subdue the other, so the two came to their senses and wisely chose peace talks, and then united to deal with the Nguyen dynasty in Vietnam.

As a result, all parts of northern Vietnam asked the capital Hue for help, and the Vietnamese king Emperor Duc was shocked. However, due to the current domestic difficulties of the Nguyen Dynasty and the Cambodian uprising that was captured more than ten years ago, the Vietnamese army was severely damaged, and it has not recovered now. Moreover, in recent years, the Western country of France began to gradually invade from the southern coastal Cochin-China area, and the originally powerful Nguyen Dynasty was now unable to face these internal and external threats alone, so Emperor Duc remembered to invite the army of the Qing Dynasty, the suzerain, to enter Vietnam to "help suppress".

But when he asked, a shocking news came: the Qing Dynasty had fallen!

Emperor Side was taken aback! He never imagined that a behemoth, such a powerful Qing Dynasty, would perish in a short period of time.

Last year, he only heard that some mobs were rebelling in the Qing territory on the border north of Vietnam, and he heard that there was a lot of commotion. But for such rebellions, in which year were there not dozens? Haven't they all been suppressed in the end? Therefore, Emperor Si Duc did not care too much, and now, for the suzerainty of the Qing Dynasty, since the war with the Siam and Cambodian rebels, the Jiaqing Emperor of the Qing Dynasty has not paid as much attention to this suzerainty as a few decades ago. Therefore, when there was a rebellion in Guangxi, he only ordered to strictly guard against the north of Vietnam and prevent the people of Yue from participating in the rebellion, so as not to offend the Qing government.

Unexpectedly, in just such a short period of time, the Qing Dynasty was overthrown. He hurriedly sent people to congratulate the new dynasty in charge of the new Huaxia country, and declared that he was willing to continue to respect the new dynasty as the suzerain.

But before there was a response, Yuebei began to be in chaos.

Two rebel forces from Guangxi continued to encroach on northern Vietnam, and even occupied most of northern Vietnam.

The one named Liu Changqing, who was still the governor of Guangxi in the original Qing Dynasty, went so far to submit to himself, and occupied the northern fishing village of Haiphong and Ji Po Island, and organized dozens of warships to attack and harass the Red River Bay from time to time.

And the one named Zhu Hongying occupied almost all of the northern Vietnamese area north of Hanoi. Now he led an army of more than 10,000 people to attack outside the city of Hanoi.

The entire Beiqi has been invaded by these two forces, and now it is even more like a two-release game to harass Hanoi.

In desperation, Emperor Duc had no choice but to send the general Chen Jiancheng again to lead an army of 10,000 people to Hanoi to support. This time, Emperor Si De was really angry, and sent 5,000 elite Janissaries of the imperial court, and then mobilized 5,000 local garrisons in the area of Annam, and rushed to Hanoi.

The Praetorian Guards of the Nguyen Dynasty were equipped with Western muskets, although they were still old-fashioned Suifa muskets sixty or seventy years ago, but they were also well-armed. Therefore, after Chen Jiancheng arrived in Hanoi, he arranged the garrison of Hanoi and led 7,000 people to take the initiative to attack northern Vietnam.

At the beginning, Zhu Hongying and Liu Changqing thought that their defeated generals were coming again, and they didn't care. Unexpectedly, after several battles, both of them suffered heavy losses. Liu Changqing is better, after all, he was born as an official of the imperial court, and he still has a few drills under his hands, and the weapons are either muskets or knives and spears, and he has inherited the fine traditions of the Qing army, and he runs away when he sees it. Zhu Hongying's rebel army was seriously damaged. His subordinates only had a small number of muskets, half of them used knives and forks, the other half were men, and even bamboo spears sharpened with bamboo poles, and there was no protection, and they also relied on their bravery, and they were beaten by the Vietnamese Janissaries for a while, and finally fled in defeat.

The two had to join forces again to discuss the method, and finally came to the conclusion that the Vietnamese army should be led into the woods for ambush.

After losing seven or eight hundred people, Zhu Hongying finally succeeded in luring the careless Vietnamese army out of the mountains and forests more than 100 miles away from Hanoi, and together with Liu Changqing, successfully ambushed the Vietnamese army. In a big battle, the Vietnamese army was killed and wounded heavily, and even Chen Jiancheng was killed by Zhu Hongying on the spot. The Vietnamese army lost 2,000 or 3,000 people, captured more than 1,000 people on the spot, and scattered more than 1,000 people, leaving only more than 1,000 people to flee back to Hanoi.

After Zhu Hongying and Liu Changqing's men captured two or three thousand muskets, their power rose sharply and they took advantage of the situation to counterattack. They took some prisoners and some of their subordinates recruited in northern Vietnam, pretending to defeat the Vietnamese army that had fled back to the city, and attacked by surprise and captured Hanoi in one fell swoop.

As soon as the city of Hanoi was broken, except for the 2,000 Janissaries of the Nguyen Dynasty who fled by the road, the rest of the Vietnamese troops surrendered one after another. At this time, the situation changed greatly, the barrier of Hanoi was lost, and the entire Red River valley area was occupied by Zhu Hongying and Liu Changqing.

Zhu Hongying and Liu Changqing took Langshan along the line of the Canghe River and went to Hanoi through Lang Shang as the dividing line, and the east of the Canghe River belonged to Liu Changqing and the west belonged to Zhu Hongying. Hanoi is managed by two people, each with half of the total.

After some conspiracy between the two, Zhu Hongying claimed to be a descendant of the royal family of the Ming Dynasty, ascended the throne in Hanoi and became the emperor, announced the rebuilding of the Ming Dynasty, the year name Annam, and named Liu Changqing as the king of Dingnan.

As a result, the two officially separated themselves in northern Vietnam.

When Emperor Si De received the news that Chen Jiancheng was defeated and died and the city of Hanoi was occupied, he was shocked and frightened. But at this time, he was no longer able to send troops to the battle.

In desperation, he had no choice but to send envoys again, with countless precious items such as ivory, gold, and pearls, to Guangzhou by sea, and then to Shengjing, the imperial capital of the Chinese Empire, to meet the emperor and ask for troops to help suppress the rebels in northern Vietnam.
