in the Han dynasty, it was said that a distant friend is close to attack, and a gentle one is far from kindness. That is to say, you can recognize me as the boss if you want. Come and pay a New Year call to the boss every year. The boss gives you lucky money, just like the Huns, who attached themselves to the Han Dynasty several times and turned against each other again and again. As a result, I can't beat it. If something is wrong, I will accompany the boss and pretend it never happened. In fact, I personally don't agree with the rule of the Han Dynasty, which was a very failed regime. Because the political system of the Han dynasty changed again and again, and it was tolerant and close again and again. It is the common people who suffer in every war. The words of the Tang Dynasty are militaristic. To put it bluntly, I will fight regardless of whether I can fight or not, although there are few victories in foreign wars in the Tang Dynasty. But the belligerence of the rulers made many foreigners remember the label of China people-Tang people. In the Song Dynasty, I was mainly engaged in the economy. I will never play with you if I can spend money. The alliance between the Northern Song Dynasty and Liao State, and the Shaoxing Peace Conference between the Southern Song Dynasty and Jin State. They all pay the premium for others every year, but the rulers of the Song Dynasty didn't care about the money at all. Because the economy in the Song Dynasty was the best in China's feudal dynasty, the gross national product (GNP) at the peak of the Northern Song Dynasty accounted for 85% of the world. By the time of Shaoxing in the Southern Song Dynasty, due to the loss of the Central Plains, the territory was limited to the South and Sichuan and Shu, but the GNP of the Southern Song Dynasty still accounted for 65% of the world. The words of the Yuan Dynasty were to broaden exchanges at home and abroad, and Genghis Khan's expedition to Sumatra by Mongolian fighters had to be withdrawn. Because they can only fight but can't defend the city, although the war failed, the Yuan Dynasty found that the world was not small, and gradually began to try to trade with big countries in the Middle East and parts of Western Europe. In fact, you may not know that Zheng He didn't go to the Western Ocean at the earliest, but someone went to Europe as early as the Yuan Dynasty. And I learned the casting technology of gold coins from there, so the gold coins and silver coins in the Yuan Dynasty were even more widely circulated than silver and silver tickets. The diplomacy of the Ming dynasty is to defend the territory, neither to cede territory nor to kiss. What's more, Emperor Yingzong was captured by Mongolia at that time, and Mongolia threatened to lure Yingzong into a chariot and drove him to Beijing to threaten Daizong to exchange Beijing for Yingzong. Yingzong was driven by knives and axes and remained indifferent. Therefore, the diplomacy and military of the Ming Dynasty were better, which not only repelled the Dutch invading army, but also helped the subordinate country North Korea to fight Japan. North Korea and South Korea are recorded in the history books as Wanli's anti-Japanese war. The only pity is that Ryukyu Island is lost, which is now Okinawa, Japan. In the Qing dynasty, it was too nationalistic, and it was completely enterprising. There's nothing to say. The treaty between Kangxi and Russia at that time was actually that Russia gave him a face to cut the land and look good, even though the place was deserted at that time.
