The word "emissary" in foreign countries seems to be different from that in China, with a certain theological color.

Here are some examples of China:

1, Zhang Qian in the Western Han Dynasty and Emperor Wu of the Han Dynasty: personally sent to the Western Regions, which opened the prelude to the western expansion of the Central Plains civilization; Presided over the southwest (Sima Xiangru is one of the envoys);

2. Ban Chao in the Eastern Han Dynasty and the Han Dynasty: Ban Chao sent envoys to the western regions and presided over the affairs of the western regions for a long time. He used various means to ensure the strategy of breaking the Xiongnu's arm in the Western Regions, and sent Gan Ying to Daqin (Rome), but stopped at the Iranian side of the Persian Gulf.

3. Shi Pei Time in Sui Dynasty: Fu Yu, divided into Turks, wrote the Map of the Western Regions, recording the astronomical geography, customs and customs of 44 countries in the Western Regions;

4. During the period of Emperor Taizong, Wang Xuance, as an envoy of the Tang Dynasty, made good use of the influence of the Tang Dynasty Empire (as an envoy of the Tang Dynasty, he convened troops from Nepal, Sikkim, Tibet and southern India to crusade against the kingdom of Makada and killed the envoys of the Tang Dynasty) to ensure his dominant position in South Asia;

5. Zheng He in the Yong Xuan period of the Ming Dynasty: I won't introduce this.

After the Qing dynasty, most of them were diplomats, and they basically had no military power and full authority.
