During the Eastern Han Dynasty, Ban Chao, a famous soldier, led troops to Shanshan in the Western Regions, and the King Shanshan greeted him very ceremoniously. But a few days later, Ban Chao found that King Shanshan was very cold to them. So he said to his entourage, "King Shanshan's attitude has changed. I think the Huns must have sent messengers, so King Shanshan hesitated and didn't know what to do. " Ban Chao immediately called Shanshan's waiter and deliberately asked him, "Where did they live for a few days after the Xiongnu emissary came?" The waiter told the truth.
Ban Chao immediately said to his men, "Nothing ventured, nothing gained! Only by attacking the Xiongnu emissary with black fire and destroying it in one fell swoop can Shanshan's idea of taking refuge in Xiongnu be broken. "That night, Ban Chao led soldiers into the Xiongnu messenger camp, set fire to the wind, so that the enemy died in flames. At the same time, Wang Shanshan was invited, and Wang Shanshan expressed his willingness to send his son to the Han Dynasty and live in harmony with the Han Dynasty forever.
