75th anniversary review of history. According to Baidu Al, Japan, the country with the longest history of founding a nation in the world, was founded in 660 BC. Although the dynasties have changed many times, such as Yamato, Nara, shogunate, militarism, etc., the emperor system has continued to this day, making it the country with the longest history of founding a nation. I wonder if it is one of them. Others such as China, Denmark, Andorra, San Marino, etc., although they also have a very long history of founding a nation, the length of time is not as long as Japan. For example, although China has a long cultural history, it has not existed as long as Japan as a unified national entity. China has experienced many dynasties in history. Denmark, Andorra, San Marino, etc. were founded about a thousand years or less, and they are not as long as Japan. $BTC $ETH $SOL We will be Tang, Song, Ming, Qing, and the Republic of China, but Japan has always been called Japan, and the emperor has not changed, becoming the longest country in history.
