Xiao He is the first hero of Khan, who has made great contributions. In those days, Xiao He fought for Liu Bangnan in the north, and also took out his own food during the war. Even Sima Qian's Historical Records recorded Xiao He's contribution to the establishment of the Han Dynasty. Premier Zhou Enlai once said, "Liu Bang fought many wars and suffered many defeats, but he suffered many defeats. He relies on what is the prime minister and takes the control as his base. He needs people and food. Xiang Yu won every battle, but he couldn't stand failure; One of the reasons for the failure is that there is no such prime minister as Xiao He ".

During the uprising of Liu Bang, Xiao He was the main planner and organizer. After the demise of Qin, Chu and Korea were established. Liu Bang ordered Xiao He to stay in Guanzhong. Xiao He restrained the management order of tax, politics, people and customs, and sent enough food and wages and young people to go, so people liked Liu Bang, and Xiang Yu refused to work, which relieved Liu Bang's worries. Liu bang established a solid rear base. Liu Bang has a full understanding of Xiao He's role. When he explained to the generals why Xiao He was listed as a hero, he said at the first time: "The contribution of the generals is to hunt wild animals and work with dogs; Xiao He refers to the beast, and his merits are the same. "

Protect the power of books. After Qin Shihuang issued a book burning order, all the Confucian classics and books contended by a hundred schools of thought were burned to ashes, and Xianyang became the only place to collect and preserve books and materials. After Liu Bang's rebel army invaded Xianyang, many generals were busy grabbing treasures and dividing up gold, silver and beautiful women. Even Liu Bang himself was carried away by victory and plunged into the palace, lusting after gold, silver, jewels and beautiful women and reluctant to leave.

Only Xiao He was indifferent to the beauty of gold, silver, jewelry and property, but he rushed to the yamen of the Qin Prime Minister's Office to collect legal classics and carefully preserve them. In the subsequent Chu-Han War and the difficult period of Liu Bang's founding emperor, Liu Bang was able to know the general trend of the world like the back of his hand, and quickly took measures to occupy the fortress and appease the people's hearts, all thanks to Xiao He's timely collection of books.
