张骞凿空西域,意外发现通过西南地区能够到达南越和西域,这也是汉武帝经营西南地区的发端。在汉武帝成功地征服匈奴与南越的同时,西南绝大部分地区被纳入到了汉朝的版图,这在中国历史上影响深远。汉武帝为统一多民族国家作出了重大贡献。 Zhang Qian hollowing the Western Regions, accidentally discovered that Southwest and Western Regions can be reached through the southwest, which is also the beginning of Han Wudi’s operation in the southwestern region. While the Han Emperor succeeded in conquering the Huns and South Vietnam, most of Southwest China was included in the territory of the Han Dynasty, which has far-reaching implications in Chinese history. Emperor Wu made great contributions to the reunification of the multi-ethnic country.
