My answer is to elicit the big guy's answer, the strength is generally limited, and the strength is purely selling strength, mistakes are inevitable, and dismissal.

Let's see what is painted on the banner used by the Oda Nobunaga family after proposing "Tianxia Bubu"?

Three Yongle Tongbao. otherThe slender flag reads "Nan no Myoho-renge-kyo".

The story of Assassin's Creed Shadow takes place at the time of Oda Nobunaga's height and demise, which means that the aforementioned banners should be visible in the game. Since Oda Nobunaga, a person from all over the world, attaches so much importance to Yongle Tongbao, it is enough to prove the important position of Yongle Tongbao in the circulation of Japan's Warring States Period.

Of course, the currency after the Ming Dynasty was harassed by the Japanese because of the decline of the national power of the Ming Dynasty, and the Xuande money seems to be visible, but the others are not visible.

Oda Nobunaga used this as a flag, probably hoping to end the war as soon as possible, and then vigorously develop the economy, so that he could enjoy great blessings. One of his economic policies was called "Rakushi Leza", which was very flattering to businessmen, such as the demolition of tariffs set by former forces in various places.

The websites and data I've studied are too limited compared to the big guys. But from the limited data I have seen, Japan has obtained and circulated a considerable amount of Chinese coins from trade since the Northern and Southern Dynasties, such as Yuanyou, Zhenghe Tongbao of the Northern Song Dynasty, and then Hongwu and Yongle Tongbao of the Ming Dynasty.

• There is a theory that the world in Japan was in turmoil at that time, and the process of minting coins was gone, and the reason was that Japan did not dig up the copper coins made by itself at that time. After Japan settled down, the Edo period finally opened Kanei Tongbao, and then a certain big guy instantly posted a bunch of Kanei Tongbao envy I can't do it.
• Another theory is that Japan has also imitated Yongle Tongbao, but due to the impact of war and technology, the value is far inferior to the genuine Yongle Tongbao, which is called "Tong Qian (びたせん)", and the people are still proud of using the regular Yongle Tongbao.

• There is also a saying that the copper coins from China are enough for Japan, so they don't need to make their own regular copper coins, but I don't believe this.

Yongle Tongbao is not only popular in China (nonsense) and Japan, but also in the whole of East Asia, parts of Southeast Asia, and even East Africa. I can only say that this is what China looked like back then, with a strong military, developed commerce, and a unified law, and the currency produced was not only of good quality but also had little weight error, and half of the world liked to use it because of China's good reputation. On the other hand, there is a certain feudal dynasty behind, ouch.

However, my country has long been minting money, this is the five-baht money model I saw when I went to the Qin and Han Museum of Shaanxi History Museum last year.

The strength of ancient China can be seen by a small copper coin.
