I don't know if you have read a paragraph, someone in South Korea published an article saying that the north of the ancient Yangtze River belonged to South Korea, and then the Vietnamese also published an article saying that Vietnam and China were ruled by river in ancient times, and the south of the Yangtze River belonged to Vietnam.
South Korea's tug-of-war application was successful
Even if the Koreans are concerned, the lack of self-confidence in their bones not only makes their plastic surgery industry very developed, but also allows them to enrich the history of their own countries by occupying the culture of other countries. Just robbing more than 50 historical and cultural figures in our country to apply for heritage has made people grit their teeth against them, including traditional Chinese medicine, Confucius and so on.

Now why do Koreans call the north of the Yangtze River South Korean? It turned out that during the Tang Dynasty, the country was slightly stronger, and the emperor was going to expedition to Goguryeo, and Goguryeo was actually related to Korea. Due to the limited conditions at that time, every crusade against Goguryeo ended in failure, including The Imperial Expedition of Emperor Taizong of Tang and Li Shimin was also a failure.

Based on this, the Korean scholar Kim Chang-chi's "Three Yuan Collection" wrote: "Qianqiu bold Yang Wanchun, arrow shooting hair falling into the eyes", the beard refers to Li Shimin, this history is of course forged. In fact, during the Wu Zetian period, Xue Rengui destroyed Goguryeo, but the Koreans thought that they had defeated the Tang Dynasty, so the area north of the Yangtze River should be considered Korean territory. They also put their own ancient maps on the history books, and the north of the Yangtze River, including Japan, is their territory.

Even if Koreans have fantasy attacks, why do Vietnamese still come to find a sense of existence? This has to start from the Qin Dynasty, when Qin Shi Huang sent Zhao Tuo and other generals to open up territory to the south, and finally included Lingnan into the territory of the Qin Dynasty. Later, after the fall of the Qin Dynasty, Zhao Tuo swore not to bow to the Han Dynasty, so he established the State of South Vietnam, which mainly included the Liangguang region and the Vietnamese region. The Vietnamese regard Zhao Tuo as their ancestor, so it is said that the south of the Yangtze River in ancient times was Vietnamese. In fact, it is more accurate to say that Vietnam used to be Chinese.

"The king lives at the head of the Yangtze River, I live at the end of the Yangtze River", the great Tang Dynasty was assigned to the Yangtze River by two countries, which really made people laugh off their teeth. Fortunately, there are still many people in the two countries who know right from wrong, and they have not applied for this matter, otherwise it is really a shame to lose face to the whole world.
