Guan Zhong also said to the Chu merchants, if you sell me twenty raw deer, I will give you a hundred catties of gold; if you buy me ten times more, I will give you a thousand catties of gold. In this way, the men of Chu lived in the wild to hunt deer, and the women lived on the road to hunt deer. Later, Xi Peng asked the people of Qi to increase their food storage by five times. At this time, Guan Zhong began to send people to close the pass and stopped communicating with the Chu State. At this time, a problem arose. The people of Chu State were busy hunting deer and did not grow food. Chu State was in short supply of food, which cost as much as 400 yuan per stone. The state of Qi then sent people to transport grain to the south of Qian for sale. Four-tenths of the Chu people surrendered to the state of Qi. After three years, Chu State surrendered. In this way, Chu State was also destroyed.

Looking at Guan Zhong's economic thoughts, his foreign economic strategies can be summarized into five aspects. "Guan Zi·Light and Heavy Armor 80" says this: Duke Huan said: 'Light and heavy I have obtained and heard about the numbers and national standards. What can I do about the use of troops? ’ Guanzi said to him, ‘Five battles will lead to the formation of soldiers. ’ Duke Huan said, ‘What does Ruoyan mean? ’ Guanzi said to him: ‘Please fight with balance, accuracy, flow, power, and momentum. This is what the so-called five battles lead to soldiers. ’ Duke Huan said: ‘Good. ’ The general meaning is that we fight on balancing supply and demand, fighting on adjusting prices, fighting on the circulation of materials, fighting on the use of power and tactics, and fighting on the utilization of the situation. He believed that in this way he could conquer the enemy without fighting. On the whole, the core of these economic warfare strategies preserved in "Guanzi·Qingchongwu 84" are to induce other countries to give up their basic industries (mainly referring to agriculture in Guan Zhong's era) by allowing other countries to exert certain industrial advantages. Its industrial structure has weakened. When the time comes, use embargo to force the other party to surrender. Mr. Ma Feibai believes that these economic tactics are specific preaching on how to destroy other countries through light and heavy strategies, and their central idea is just a conspiracy, that is, using the principle of "the world is high, I am the best" to reduce the domestic price of a certain foreign specialty. The method of raising the country to a higher level than that of the producing country is to turn it into a colony or semi-colony with a single economy.

The main idea of ??economic warfare is to defeat the enemy without fighting. It is a strategy in military warfare and a competition between masters. It is of great significance to China’s actual anti-economic war. Today, international commodity prices remain high. The United States and other Western countries control global agricultural products, mineral products, energy and other economic resources, and have the pricing power of various commodities. For example, the iron ore pricing incident that occurred last year and the rare earth fire sale incident in recent years have shown that some industries in China have been seriously controlled by others. The reason is that China does not pay attention to the importance of priority and does not know the end result. The propositions of "Guan Zi: Light and Heavy Chapters" played an important role in the economic life of the Han, Tang and Song Dynasties. Today, when our country is pursuing a socialist market economy, especially when countries are rising and competing, the Warring States Period thousands of years ago Strategies can still alert us, and their importance and lessons learned are self-evident.
