In recent years, a mysterious japanese group, the Yin-Yang Division, has become widely known with the popularity of anime and games.
This organization in history did exist and belonged to the imperial court institution "Yin Yang Liao".
However, few people know that the emergence of the Japanese Yin-Yang Division is closely related to China and the Korean Peninsula.
At that time, in the southwest of the Korean Peninsula, there was a state called Baekje, which had been married and allied with Japan for generations.
In 553, Emperor Shumei of Japan asked Baekje for an almanac and a doctorate, and succeeded in obtaining it the following year.
This was the beginning of the introduction of the so-called divination to Japan.
In fact, Baekje's study of divination and almanac was all learned from the Southern Dynasty during the Southern and Northern Dynasties.
In the Book of Song, it is recorded:
In 450, King Baekje sent envoys to the Southern Dynasty Song Emperor Wen for "Yilin" and "Shi Zhan".
In other words, Japan indirectly learned the yin-yang number culture of Jiangnan.
The calendar that Japan learned from baekje is actually the Yuanjia calendar of the Southern Dynasty and Song Dynasty.
After entering the 7th century AD, the Tang Dynasty arose and successively destroyed goguryeo and Baekje on the Korean Peninsula.
Some of the remnants of the two countries, who did not want to belong to Datang, fled to Japan.
In 660, the remnants of Baekje, led by Onifukunobu, welcomed Prince Buyeo Toyohe, who had previously been a hostage in Japan, as the new monarch, and gathered the remnants of the country to try to revive Baekje.
Emperor Qi of Japan and his eldest brother Sent Tens of Thousands of Troops Across the Sea to the Korean Peninsula to Support Their Restoration.
However, in 663, at the Battle of Baijiangkou, the Japanese army was defeated by the Tang Dynasty.
After baekje's restoration was hopeless, a large number of skilled nobles were highly valued in the Japanese imperial court.
For example, Jiao Fumu, his specialty is "idle yin and yang".
In the "Nihon Shogun", it is recorded that in 692 AD, the Emperor of Shōgun rewarded The Yin-Yang Doctor Shamen Dharmazang with 20 taels of silver.
This Shamen Dharmagu is a Baekje man who went into exile in Japan during the reign of Emperor Tenchi.
In addition, there were Also Yinyang Liao officials such as Gao Jinzang and Wang Chinese, who also came from goguryeo and Baekje in the fallen kingdom.
It can be seen that the early Japanese Yin-Yang Liao completely relied on the knowledge of the Yin-Yang Magic Number of the Watanabe people to operate.
Gao Jinzang was recorded as proficient in astronomy in the "Examination Accounts of Officials", and Wang Chinese had the same specialty.
Even the later Emperor Tenmu himself was good at astronomy and armor.
It is enough to see that the Yin-Yang Liao officials are highly skilled.
In fact, in addition to traditional books such as the Zhou Yi, the Yin-Yang master must also be proficient in astronomical records and calendars in various Chinese history books.
For example, the "History of Tianguan Book", "Hanshu Astronomical Chronicle", "Jinshu Legal Calendar" and so on.
It can be said that every Yin-Yang master is a Chinese master.
After entering the Heian period, the Yin and Yang masters gradually appeared in the court as spellcasters to solve disasters for the royal family.
That's what we know now.
