China has many titles in ancient times, but the longest used is the Huaxia and Zhou Dynasties, the princes who attach importance to etiquette and observe etiquette and righteousness, called Zhuxia, in the ancient zai, "Huaxia" is the Central Plains, and the four sides are "Yi Man Rong Di", which is recorded in the "Left Turn": The descendants do not seek Xia, and yi do not chaotic Hua.
Yanhuang and Huaxia lasted for more than 5,000 years, but "China" is a relatively modern word, and in September 7, 1689, Qing Kangxi and Tsarist Russia signed the Treaty of Nebuchu to demarcate the border of Heilongjiang, and when using the name of the country this time, the Qing Dynasty used the word "China" for the first time.
After the fall of the Qing government, the Republic of China was also called the "Republic of China", and China gradually became the name of our country, but there is also a place called "China", the bank here is called the Bank of China, the power company is called China Electric Power, and even the government is called a branch of China, this place is Japan.
Although Japan and China are neighbors, how can our "China" have anything to do with Japan? There is a place in Japan called "China Region", and this China is not China in the traditional sense, "China Region" is a concept of Japanese territory.
The Chugoku region, located in the western part of the Japanese island of Honshu, consists of five prefectures, Namei Prefecture, Shimane Prefecture, Okayama Prefecture, Hiroshima Prefecture, and Yamaguchi Prefecture, with an area of 31,917 square kilometers and 7.718 million people.
The earliest record of the "Chinese region" is the "Taiping Chronicle" of the Southern and Northern Dynasties of Japan, but the "Ancient Chronicles" and "Nihon Shoki" of the Japanese Imperial Family also have the title of Reed China, which was referred to as Nakatsu Kingdom and China at that time, which may be the earliest record of Japan's "China", but it is still vague.
After the Southern and Northern Dynasties, the Sui Dynasty was briefly unified, and in 607 AD (the third year of the Sui Dynasty), Japan sent an emissary to the Sui Emperor saying: The son of heaven at sunrise to the day of the book is not where the son of heaven is unharmed. Japan called himself the Son of The Sunrise and the Emperor of the Sui Dynasty the Son of the Sunset, which made him very unhappy, and the negotiations between the two countries eventually broke down.
Until 630 (the fourth year of Tang Zhenguan), Japan first came to the Tang Dynasty, in more than two hundred years, Japan sent a total of 12 emissaries, Japanese culture is also deeply influenced by Tang culture, even the Japanese name is the Tang Dynasty "gift", in these 12 dispatches to the Tang Dynasty, Japan introduced a lot of poetry.
These poems also play a decisive role in the Japanese era names, "Heisei" is from the "History of the Five Emperors": "Inner Peace outer cheng", Shangshu also has "Jihei Tenseong", among the 247 japanese era names, most of them are from the "Four Books and Five Classics", and the latest era name is "Reiwa", from the ancient Japanese book "ManyoJi".
In summary, it is normal for Japan to borrow Tang culture and change a region to "China region", but after Japan's defeat in the war, in order to maintain its image, "China region" is rarely used, and it is collectively referred to as "Shanyin Shanyang area".
