There are many such cases, both in China and foreign countries, to name a few
Britain: King Arthur
King Arthur, whose full name is "Arthur Pendragon", was the "King of Britain" during the reign of the ancient Roman Empire in England, and he also had the reputation of "King of Eternity". King Arthur led the Celts, not only against the Romans, but also against the Anglo-Saxons. He had an invincible sword called the King's Sword, and he had a group of loyal and brave companions called the Knights of the Round Table.
The story of King Arthur is famous throughout the European world, and even the 150-member Knights of the Round Table are also famous, and their stories of indomitable and bloody battles have become a symbol of "faith, courage and loyalty" of Europeans. From the Middle Ages to the present, many subjects come from King Arthur. Many people can't help but think that King Arthur is a real historical figure.
How strong is the impact? The "Arthur" who holds a great sword in the glory of the king is based on King Arthur.
As everyone knows, there is no historical record of King Arthur, and there is no evidence of his existence at present. Where did King Arthur's story come from? Legendary myths from the Celts were later carried forward by fantasy novels
[China's most famous] mink cicada, mulan
"Sinking fish and falling geese, closing the moon and shy flowers" refers to the four beauties of ancient China. Among them, the "closed moon" corresponds to the mink cicada.
However, "sinking fish" Xi Shi, "falling goose" is Wang Zhaojun, "shy flower" Yang Yuhuan, one by one are recorded in historical materials, and each one is a reality show. The love triangle of Sable Cicada, Lü Bu and Dong Zhuo can be said by almost everyone. People originally agreed that the "mink cicada" did have its own person.
Unfortunately, this mink cicada alone is the fictional female number one in the Romance of the Three Kingdoms.
The deeds of Hua Mulan's "surrogate father and military service" have been passed down for more than 1500 years and have always been a symbol of the folk "hero of the towel". People often think that there is a real person, often compared with another heroine, Liang Hongyu. Coincidentally, like Arthur, Sable Cicada and Mulan also became the game characters of the Glory of the King.
However, it is also a pity that Mulan only appears in the folk song "Mulan Ci", and history really does not record such a heroine.
[The most nonsensical] Korean: Tanjun
Tan Jun, this is the ancestor of the Korean Dynasty. According to the records of the Korean Dynasty, around the time of our Yanhuang Dynasty, Tanjun not only established the ancient Joseon Kingdom, but also lived for 1908 years, and finally did not die, directly living in seclusion and incarnating as a god.
In the 1200s, the ancient Korean book "The Relics of the Three Kingdoms" began to record the story of Tanjun. By the 1300s AD, there was another "Imperial Rhyme" to talk about Tanjun. In the 1990s, it was even more bizarre, and people said that the remains of Tanjun had been found and buried thickly. Since then, the dprk and the Roks have written this as a history of letters into textbooks, and who dares to doubt and be anxious with whom.
The things of Tanjun are all myths at first glance, but the people of the korean and Korean families really believe it. However, people said that according to the ancient kingdom established by Tanjun, the northeast has been the boundary of people since ancient times.
