As the saying goes, such a big situation in the world is an inevitable condition for a long time to be united and long to be divided, especially for our China, which has a long history, national reunification is not only our historical mission, but also a task that our China is deeply rooted in our bones.

It is precisely because of the unremitting efforts of successive emperors that since the Qin Dynasty, China has always been a super power in the East, whether in terms of force or culture, it has reached the world's top super level. At the same time, China also has the mindset of a wide range of people, and tolerates and accepts all kinds of foreign envoys who come to the DPRK for advice, as long as our country's personnel give a little guidance, no matter which country around it can benefit a lot.
China's famous economic belt Silk Road naturally needless to say, in that year the grand situation has fully let other regions and countries feel the strong national strength of our China; by the time of the Tang Dynasty, China's prestige has become more and more famous, and it seems that it has become a spokesman for the East, and all countries have become greater than the Tang Dynasty.
Even at the end of the Qing Dynasty, for those other neighboring countries bordering China, the weak Qing court still had the greatest right to speak and a great prestige.
There was once a Southeast Asian country that asked the Qing dynasty court to give it the name of the country for approval, and the Qing emperor felt that the name of the country was not good, so he reversed the name of the country, so the country did not dare to say a word, and after he deeply accepted the name of the country, the name of the country has been used until now.
This small southeast Asian country is located in the northern part of the Indochina Peninsula, bordering guangxi, Guangdong, Yunnan and now northern Vietnam in China, and their land area is only 330,000 square kilometers, and some of their land has long belonged to our China in history.
According to historical records, since Qin Shi Huang unified the Six Kingdoms, he continued to send troops to the outside world, sending large armies across the Lingnan region, conquering and occupying the areas of present-day Guangdong and Guangxi, and subjugating the local Baiyue tribes, which was very strong. In order to effectively manage the area, Qin Shi Huang established three counties here, of which Luo Yue (northern Vietnam) was administered by Xiang County.
However, during the last period of the Qin Dynasty, South Vietnam gradually fell out of the control of Qin Shi Huang, and zhao Tuo, the Qin Dynasty's Nanhai lieutenant, established himself as the main ruler and made the South Vietnamese region independent. In 111 BC, Emperor Wu of Han's huge army moved south and incidentally destroyed the State of Nanyue, always submitting to the territory of China.
For more than 1,000 years, north-central Vietnam has always been our Chinese territory, no matter how the change of administrators and rulers within South Vietnam, no matter how fierce the mutual conquest between them, but they have always been under the management of China, and they dare not raise the mind and small ideas of rebellion.
However, everyone is ambitious, and South Vietnam is certainly no exception. From 1531 onwards, South Vietnam was divided into two dynasties, divided into the Lê Dynasty and the Mo Dynasty, and from then on entered a period of more than 200 years of north-south division, and after years of fighting, they gradually evolved into a war between the Zheng family and the Nguyễn family, which is known in history as the "Zheng Nguyen Dispute".
It was not until 1802 that Nguyen Phuc Anh, a descendant of the Nguyễn clan, established the Nguyễn Dynasty with the support of the French, completely ending the internal rivalry between the two dynasties. Because the South Vietnamese region has been a vassal state of China from ancient times to the present, Nguyen Phuc Anh immediately sent emissaries to China in 1803.
At that time, the Nguyen Dynasty was under the administration of the Qing Dynasty Court, and even if Nguyen Phuc Anh established the Nguyen Dynasty, all specific matters after that had to be consulted by the Qing Dynasty Court. The purpose of the Court of the Qing Dynasty this time was to request that their name be changed to "South Vietnam".
The Jiaqing Emperor did not like the name "South Vietnam" at that time, believing that their name of "South Vietnam" was the root cause of the region's continuous contradictions for more than a thousand years. Therefore, he did not agree to Nguyen Phuc Anh's request, and angrily said: Reverse the name of the country.
Therefore, Nguyen Phuc Anh changed the name of the country to "Vietnam", and later, Jia Khanh also crowned Nguyen Phuc Anh as "King of Vietnam". Since then, Vietnam has used the name to this day, and it has not changed since ancient times.
This small country asked China for advice before changing its name, which further demonstrated our country's position in history. In fact, at that time, it was not only Vietnam that China gave us names, but also Korea, Japan, South Korea, Burma and Bhutan, Germany, which were vassal states of our country, and the names of the countries were once canonized by the emperors of ancient China, and the names of these countries are still in use today.
At that time, the surrounding countries believed that it was a great honor to wait for the reward of the Chinese emperor, so the neighboring countries would regularly send emissaries to meet the Chinese emperor. Looking back at the glorious history of the most prosperous period of ancient China, thinking about it now makes people feel sighing and sentimental!
