Like China, India is an ancient country with a long history. Indian Buddhist culture has also attracted Buddhist disciples from all over the world to study. For example, the Tang Priest in China went to India to learn Buddhist scriptures. But Indian culture is not just here. In the heyday of the Tang Dynasty, a little thing caught Li Shimin's attention. During the Zhenguan period, Li Shimin sent Wang Xuance, an envoy to India, and met the rebels who robbed him and fought a battle. And brought India's sugar-making technology, because sugar-making produced an iron pot industry and a white sugar industry, attracting countries to purchase, so it earned a lot of money.

First,? Fight? Li Shimin sent Wang Xuan to India to visit the monarch of Mejietuo for the good things during Zhenguan period of Tang Dynasty. I didn't expect to catch up with the death of the Indian monarch as soon as I got there. At that time, there was a riot in India, and the rebels who robbed the red eye accidentally robbed the task. Wang Xuan led the troops to arrest the rebels and took the rebel leader back to Chang 'an to go to jail. On the outside, it seems that the Tang Dynasty protected peace in India, but the purpose of this mission is to learn Indian sugar-making technology. At that time, Indian sugar was the best sugar in the world. Moreover, in India, as long as there is a small-scale temple, sugar-making technology can be made. Because of this battle, the obstacles to learning sugar have been cleared. So Wang Xuan led a sugar expert back to Datang, and the sugar technology developed by Datang was even better than that of India.

Second, the iron pot industry produced by the sugar industry earned enough money. With the rapid development of sugar industry, a convenient tool for boiling sugar-wide pot came into being. The wide pot has high heat resistance, flame resistance and durability. At that time, the smelting technology in other countries was not perfect enough. Therefore, the iron pot of Datang has become a treasure in international trade. In Europe, the iron pot of Datang is a family heirloom of the nobility. Since the lifting of the maritime ban, the value of wide pots has risen. As long as you sell a pot of 70 cents of silver in China, it costs one or two cents to sell it to the island country, and the farther away it is, the more expensive it is. With traders from all over the world coming to China to buy pots, the iron pot industry has made enough money for foreigners in China.

Third, the improvement of sugar-making technology has driven economic benefits. With the continuous research and development, there has been a great breakthrough in sugar production technology. China can make white sugar by soaking sugar in yellow mud. This technology seems unremarkable now, but at that time, only nobles could enjoy white sugar. Through this technology, it can be mass-produced and enjoyed by ordinary people. Eating sugar is a necessity in every country, especially in Europe at that time. White sugar is a rarity, and nobles can only eat a little when they are sick. With the cancellation of the sea ban, the sugar sold abroad soared by 10 thousand tons and sold at sky-high prices. Therefore, the profit of sugar sold abroad makes China earn enough money from westerners every year.

From the Zhenguan period of Tang Dynasty, Li Shimin sent envoys to India to bring sugar-making technology. The improvement of iron pot industry and sugar-making technology promoted the market economic benefits for China and brought great wealth to China. It is precisely because of the ancient people's open learning attitude that they can get so much wealth and benefit the people of China for thousands of years. The strength of a country depends not only on its strong military strength, but also on its core technology.
