In the late autumn of 196 BC, Liu Bang, the former hero of cloth and now the Han Gaozu who ruled the world, finally defeated the last prince with a different surname, Wang Yingbu, and completed his great mission. He returned to his long-lost hometown of Pei County, where his dream set sail. 
Recalling that year, when Liu Bang left Pei County, he was penniless and destitute; And today, he is already an emperor who has experienced a hundred battles and has the power of the world, and his achievements have surpassed the imagination of countless people, and also realized the dreams of countless men. He was very excited, so he invited his childhood friends and villagers to the palace in Peixian County, and held a sumptuous banquet to celebrate this rare reunion moment with them. 
After three rounds of drinking, Liu Bang couldn't help but be full of pride, and he improvised the "Song of the Great Wind" that has been passed down through the ages. The passionate melody and bold lyrics seem to be a portrayal of his life. Then, he generously announced: The people of Pei County will never have to pay taxes from now on! This news is like a spring breeze, blowing the land of Pei County, making the people happy, as if they are celebrating a festival. 
However, history is always full of drama. According to historical records, "Pei County" at that time actually included two cities: Pei County and Fengyi. Fengyi is Liu Bang's birthplace, and Peixian is his place of work as an adult. Therefore, when Liu Bang announced the tax exemption policy, it only targeted Peixian County and did not include Fengyi. Behind this subtle difference, there is an untold story. 
It turned out that the people of Fengyi had betrayed Liu Bang and left him homeless. This incident became an eternal pain in Liu Bang's heart. Although the people of Fengyi later submitted to Liu Bang, the scars in his heart were difficult to heal. Therefore, when announcing the tax exemption policy, he deliberately excluded Fengyi, which can be regarded as a kind of relief from the past. 
As for the Yongya who betrayed Liu Bang, he is actually Liu Bang's countryman and friend. However, after Liu Bang became the king of Han, Yongya chose to betray him and took refuge in Wei. This behavior made Liu Bang heartbroken, but he could not let go. In 204 BC, after Liu Bang established the Han Empire, he began to give knighthoods to meritorious heroes. In order to appease people's hearts, he decided to seal the Yongyan that everyone knows and hates the most. That way, others have nothing to complain about. 
Although Yongya betrayed Liu Bang, he later returned to the Han Dynasty. Liu Bang named him the Marquis of a Thousand Households, so that he could enjoy his old age in peace. This story teaches us that history is always full of complexity and drama. Although Yongya was Liu Bang's countryman and friend, his betrayal and later submission became part of history. His story also shows us that although some people do not have simple backgrounds, their choices and actions can have a profound impact on history. 
At the same time, Liu Bang's mind and wisdom also make us admire. He was able to reward Yongya regardless of previous suspicions, showing the demeanor of a great leader. His story teaches us that in the pursuit of our dreams, we must not only be brave enough to face difficulties and challenges, but also learn to be tolerant and understanding of others. Only in this way can we truly realize our dreams and create a more brilliant future.
