My uncle sent me a short message, "Learn to be a volunteer in the final army and aspire to be a Changfeng". What does this mean? How to reply?

The final army has made some achievements in maintaining centralization, stopping the separatist regime of governors and resisting foreign invasion. He successfully sent envoys to Xiongnu and South Vietnam. At that time, South Vietnam refers to the ethnic minorities living in Guangdong and Guangxi. At the end of the Qin Dynasty, Longchuan, South Vietnam, made Zhao Tuo attack Guilin and Xiang Jun by taking advantage of the peasant war and establish himself as the king of South Vietnam. After the establishment of the Han Dynasty, the relationship between South Vietnam and the Han Dynasty was good and bad. Before the last army went to South Vietnam, he asked Emperor Wu of the Han Dynasty to give him a "long tassel". If the South Vietnamese King refuses to submit to the Han Dynasty, he will capture the South Vietnamese King alive with a long tassel. Since then, the story of the weak crown of the final army has become a historical story, and "volunteering" has also become synonymous with joining the army to serve the country. Finally, after the army arrived in South Vietnam, it made a speech and argued, and finally made the king of South Vietnam agree to submit to the Han Dynasty. In the fifth year of Ding Yuan (1 12 BC), the final army, who was only in his twenties, was killed by South Vietnamese Prime Minister Lu Jia, and was called the "final son" at that time. Your uncle should let you learn this spirit.
