Xu Ping was not unfamiliar with what Wang Wen said. His historical knowledge learned in his previous life was a bit unfamiliar with "Shogguan", but later the "shogunate" with the same nature became very familiar. This is a tradition in Japan. During the "Dahua Reform Reform", the king joined forces with the nobles to kill the powerful ministers to seize power, and since then he changed the country's name to "Japan", and finally became a king with real power. But after a few years, the heroes of "Dahua Reform Reform" set up the king again, and history completed a cycle of reincarnation. Later, the emperor took power back, and then committed suicide crazily, and finally became a mascot.

According to social existence, the country of Japan has no foundation for unification. The so-called centralization is nothing more than learning to walk along with Handan, China. Later, the reform once again brought the emperor up, and it was just learning the East and the West, and it was forced to go. If the emperor wants to be a real emperor, he must commit suicide to the outside world, otherwise he must be a mascot.

However, after hearing Wang Wen's words, Xu Ping still didn't understand and asked him: "There are many small islands in Japan, and there are many mountains. I know that the land is broken. There are many powerful vassals in this broken place, which is difficult to get together. But you also said that they are now the Fujiwara family, and they are the de facto people in power, and they like Zhongyuan goods, so why don't they want to trade?"

Wang Ji said: "The officials of Ducao are figures in the Celestial Kingdom. It is reasonable to not understand these barbarian and small countries. Although the Fujiwara family is the first powerful family of Japan and holds great power, they are far from being able to say anything in their country. There are countless small vassals in that country, and many of them are so strong that they can compete with the Fujiwara family. In recent decades, there have been constant civil strife in their country. Just two years ago, the official "Ping Zhongchang Rebellion" was quelled. This Ping clan is also a surname in their country. In the previous life, a Ping general's rebellion was made and became king. After pacifying Ping Zhongchang, many people died after fighting for three or four years.

.Xiao Ke said this because he wanted Ducao to understand that it was the Fujiwara family in power, but it was just a co-lord. There were quite a few powerful vassals under him that could threaten their family. If they had contact with the Central Plains, the Song Dynasty knew about the truth and support the powerful vassals, and it would be easy to change the dynasty. With this concern, Japan had banned its interactions with the Central Plains since the fall of the Tang Dynasty. During the Five Dynasties, Minyue sent envoys to him. Although he treated him with courtesy, he refused to communicate. Even the envoys of Minyue only asked the ships to return by sea merchants, which shows how deep the defense was."

Xu Ping nodded and finally understood something. The Wang Wen family was a big family in the Minyue Kingdom during the Five Dynasties. They knew very well about these things and were well aware of them.

After all, Japan actively interacted with the Central Plains during the Tang Dynasty and sent Tang envoys to the Central Plains. The Tang Dynasty adopted an open attitude towards the barbarians around it. Not to mention Japan, even many places occupied by the Tang army in the north did not change the original social system and economic culture. Especially in the fourth year of Zhenguan, the Tang Dynasty's internal debate on the policy of barbarians and Xia, and the faction of strict defense of barbarians and Xia, led by Wei Zheng, ended completely and failed. Emperor Taizong of Tang Li Shimin happily accepted the title of "Tian Khan" and officially formed one country, two systems. The Central Plains region used the Han system, and the supreme ruler was naturally the emperor, while the Hu people continued to use the Khan system, and Li Shimin used the Central Plains Emperor as the Tiankhan as the Tiankhan. Since Li Shimin, the official title of Emperor Li Tang was Emperor Tiankhan.

This was a very important change in Chinese history, which changed the trend of the Five Barbarians entering the Central Plains and actively becoming sinicized. Before seeking to seize the throne, they were called "Heaven King" and then emperor according to the custom of the Han people. It started the tradition of the Central Plains emperor of the Tang Dynasty actively adapting to the Hu regime and accepting the title of "Tian Khan", the supreme ruler of the Hu people. Later, it appeared again, the Yuan Dynasty, which was the Yuan Dynasty, which was the Mongolian Khan and the Central Plains Emperor, and the Qing Dynasty, which was later the Jin Khan and the Central Plains Emperor.

"Tiankhan" did not start with Li Shimin. It was originally the title of the supreme ruler of the Hu regime on the grassland, but Chinese classics are generally transliterated as "Dengli Khan". It was not until Li Shimin officially accepted "Tiankhan", because Dengli originally had the meaning of heaven. In order to show the difference, the Chinese language changed the previous word. The Hu people's words were actually no different from "Dengli Khan".

What Li Shimin accepted was not just a title, but a system. That is, in Hu areas, the Khan system continued to be implemented, and the officials there continued to be hereditary, not the Han system, and the central government did not send officials. The Tang Dynasty issued official documents to it, and the emperor's claim to be "Khan" or "Tian Khan". In fact, it was to divide the territory of the Tang Dynasty into two parts, the traditional Han area acted according to the Han system, the Hu people in the grassland and desert acted according to the Hu system, and the ruler of the Tang Dynasty held two positions. According to Xu Ping's previous life, the Tang Dynasty had one country, two systems, and the Han system and the Hu system ran side by side.

Li Shimin was definitely not a whim, but had a clear understanding of this. When the Hu tribes were given the title of "Tian Khan", he said very clearly, "Are I following the Khan's affairs as the emperor?" The emperor is the supreme title. Anyone who adds a suffix and prefixes to this title will demote himself. Li Shimin himself also thought so. However, he finally accepted the title and continued to use it until Emperor Daizong of Tang Dynasty was the Emperor Tian Khan, ending in the bloody purge of Chang'an by the Hu tribe.

According to Li Shimin himself, there are two reasons. One is that his mother and wife are both Hu people and have "incense" with Hu people. Another is that "Since ancient times, they have been valued by China and barbarians, but I love them alone" shows that they are different. In terms of interests, the Li family, who ascended the throne, did not have a deep foundation in the Central Plains, and Li Shimin killed his brother and forced his father to seize the throne. Such a political force was needed to balance the political power in the traditional Han area. It was precisely this policy factor that happened that during the prosperous Tang Dynasty, a large number of Han areas were transformed into Hu people, and a large number of Han people were transformed into Hu people.

This is like cutting flesh and feeding wolves, and feeding the Hu people with money, grain and wealth from the Han land, and eventually the flesh and blood were gone but the wolf was still not satisfied. The two Hu people An Lushan and Shi Siming rebelled, and then used the strengthening Hu people's military power. In fact, at that time, the Jiezhen, which was under Emperor Xuanzong of Tang, had basically no Han people in command of the army.

Under this policy background, only the small country like Japan, such as the four barbarians, would be assured and bold as to interact with the Tang Dynasty without worrying about being overthrown by the Tang Dynasty. After the bloody lessons brought by the wars in the north, the Central Plains regime once again strictly defended the barbarians and the attitude towards the surrounding barbarians became stricter, and the contact with the surrounding areas was interrupted.

The defenses of the Yi Xia in the Song Dynasty were much more severe than those of the Tang Dynasty. No matter how big the titles of foreign officials were, they were all ranked after Han officials. Even if the barbarians were granted the titles of the third duke, they would still be subordinates when they met the magistrate. In the areas where the British and Han dynasties lived in the northwest, Han women were not allowed to be slaves or concubines for Hu people, and there was no similar restriction.
