Ban Chao's bravery and eloquence were quickly taken by Dou Gu, a captain in the car, so Ban Chao became a fake Sima Lingbing to fight Yiwu. The first time he went to war, Ban Chao showed extraordinary military capabilities, so Emperor Han Ming began to reuse Ban Chao, and then Ban Chao began to go to the Western Regions. During the reign of Emperor Wudi of the Han Dynasty, the relationship between the Western Regions became worse after Wang Mang came to power. It is a dangerous road for Ban Chao to go to the Western Regions, and Ban Chao came to Shanshan for the first time. Soon after his arrival, a messenger came from the northern Xiongnu. Ban Chao killed the Xiongnu emissary and burned hundreds of Xiongnu with the mentality of nothing ventured and nothing gained. After that, Shanshan surrendered. Since then, Ban Chao's iron fist policy has been appreciated by Emperor Han Ming, so Ban Chao has been responsible for sending envoys to the Western Regions. This time, Ban Chao came to the Western Regions, settled in Le Shu first, and then got through the Southern Road of the Western Regions, put down the rebellion of Yan Qi King and established a new king. Since then, 50 countries in the western regions have surrendered one after another. Ban Chao, who lived in the Western Regions in 3 1 year, is over 70 years old. He is afraid that he can no longer govern the western regions, and he misses his country very much. So he told Emperor Xiandi that he was willing to step into this country when he was alive, even if it was Yumenguan, and asked Emperor Xiandi and Emperor Wudi to send someone to replace him. After the handover, Ban Chao returned to Luoyang in August on 102, but died in September.
