Guan Zhong's series of triple deadly tricks easily defeated Lu and Chu. How did he do it?

Guan Zhong's three-chain killing trap was used very well, and even the king of Chu was completely kept in the dark. First, he lured Chu kings and Chu people with money, making them abandon state affairs and concentrate on expanding the state treasury; Make people abandon agriculture and concentrate on catching wild deer. Then when Chu was short of food, Guan Zhong organized Qi troops to attack Chu and cut off its support. Finally, Qi gave extensive help to the fleeing Chu people, gave them food, and bought the hearts and minds of the Chu people.

First of all, let's talk about Guan Zhong's first plan: Guan Zhong ordered the soldiers of Qi State to build a house on the border of Chu State. In this house, he bought a large sum of money from the wild deer of Chu State. At that time, Chu people thought Guan Zhong was just joking. A few days later, Guan Zhong sent an envoy to advance 20 million yuan to the King of Chu (to buy wild deer). The king of Chu thinks that Qi is just trying to please Chu (because wild deer not only harms crops, but also has no practical value). Subsequently, Guan Zhong posted a notice directly outside the house: the purchase price of wild deer is 80,000 yuan, regardless of size.

Then came Guan Zhong's second plan: during this period, Guan Zhong ordered Qi to hoard grain for a rainy day. Why is this? Because all the people in Chu have gone hunting and there are no crops, the grain depot in Chu will be empty. Moreover, the "urgent need" that Guan Zhong said refers to the opportunity for Qi to attack Chu. At that time, Guan Zhong could not explain clearly, so as not to affect his third plan.

Guan Zhong's last plan: When Chu's grain depot was empty, Guan Zhong ordered his troops to attack Chu and cut off the back road. The Chu people had no food and fled to Qi. In this case, Chu had to bow to Qi.
