Because ancient Korea attached great importance to fables, fables played an important role in philosophy, religion, politics and education. The theory of tortoise and rabbit is a prominent example. According to the Records of the Three Kingdoms, Silla Minister Jin Chunqiu asked to send an envoy to Koguryo, but was imprisoned by Koguryo and will be killed. After listening to the fable "The Race between the Tortoise and the Rabbit", he understood the meaning, so he wrote to King Koguryo and promised to give up his land after returning to China. The king believed it and sent someone to send him abroad. After Jin Chunqiu left Koguryo, he said to the guards, "I came for help, but the king didn't agree. On the contrary, he demanded the land of our country. I can't promise to give up my land alone. The book I read before was just to save my own death. " King Koguryo listened to the report of the escort and wanted to launch an attack, but when he saw that Silla was ready for the army, he had to stop. This fable saved Jin Chunqiu, minister of Silla. Because he did not live up to his mission, he was elected as the 29th king of Silla after 1 1 year. Later, Jin Chunqiu sent messengers to the Tang Dynasty for help. Finally, with the help of the Tang Dynasty, Baekje and Koguryo were eliminated, the peninsula was unified, and the Silla Dynasty was established, and it was acclaimed as the first king of Silla Dynasty. This fable has played a political role of "prospering the country with one word", and its political role is so great that it is improvised, which is quite similar to the fable of the Warring States policy.
