Everyone has their own name, and the name is taken by the parents or elders when they are born, but the surname is a continuation of the family. China's surnames have a long history, and the eight ancient surnames in China have basically lasted for more than 5,000 years, and thousands of surnames have been derived from these eight surnames. Today, there are 5662 surnames in China, the majority of which are also commonly used, which are basically single surnames. In China, there are also multiple surnames, but there are three surnames that are the least Chinese, but many people use them in Japan.
The first surname is Higashino, which is more commonly used by Japanese people until now, and the famous one is Keigo Higashino. But in fact, the surname Dongye originated in China, from the Ji surname of the eight surnames in ancient times. The surname Ji came from the Yellow Emperor, because the Yellow Emperor lived in Jishui for a long time, so he changed his surname to Ji, and the Tianzi of the Zhou Dynasty in China was surnamed Ji.
After Ji Fa, the King of Zhou Wu, destroyed Shang and became the Yellow Emperor, he was to divide the meritorious men, and Ji Dan wanted to stay and assist the emperor, so he gave his son the title, and the eldest son was given the title of Duke of Lu. Duke Lu had three sons, and because the third son was given to Higashinoda, he took Higashino as his surname. This is the origin of Higashino's surname. However, the later development was not very good, and the surname Dongye was relatively rare in China.
Wooden gate, the surname is relatively rare in China, and its origin is not stable. According to historical records, this surname is said to originate from the Wei surname, and the Wei surname is from the Ji surname. During the Spring and Autumn Period, there was a Wei Doctor named Mumen Zigao, who was a person with this surname. By modern times, the surname is almost non-existent, and fewer than a thousand people have it.
The last one is Niigaki, speaking of this may still be remembered by the Japanese, the more famous one is The Shingaki Knot. This surname has existed for a long time in China, and it also originated from the surname Ji. According to historical records, the surname Xinyuan should be a descendant of Duke Bi, who was the fifteenth son of Ji Chang, who was the ancestor of the Bi surname, and had been wholeheartedly assisting the emperor since Emperor Wu destroyed the Shang.
Bi Gong was enfeoffed in Xinyuan and later developed into a surname. During the Warring States period, there was a general Xinyuan Yan, a general of the State of Wei, after the 400,000 soldiers of the Zhao army were killed by the Qin State Pit, The New Yuanyan instigated the King of Wei to support the Qin Dynasty as emperor, and after being advised by Lu Zhonglian, he stopped, and here The New Yuanyan was also called Xin Yuanyan. In the Western Han Dynasty, there was also a fraudulent emperor named Xinyuan Ping, who deceived Emperor Wen of Han in a ghostly manner, and finally was exposed by The Minister and the Ting Wei and was exterminated by the Three Tribes.
Japan is greatly influenced by Chinese culture, and there were descendants of Liu Bang who went to Japan to develop, and derived the things of Japanese surnames such as Pingyuan and Dazang. Japan had many contacts with China as early as their Yayoi period, when China was the Han Dynasty and paid tribute to the Han Dynasty. During the Tang Dynasty, there was more contact, and the Jian Zhen monk crossed the east six times, bringing a lot of Chinese culture, so it is not surprising that the surname is the same.
