The Jin army began to retreat the next day, and the Tokyo defense battle ended. Song Qinzong rewarded Tang Feng, Liu Weichen and others for their merits in defending the city, and were promoted and ordered to command five thousand troops.
Returning to the station, Liu Weichen saw that Tang Feng was unhappy, so he asked: "Commander, the Jin Army has retreated and we have been promoted. Why are you unhappy?" Tang Feng said: "The Jin Army only retreated temporarily, and they will come back. I have thought about it these days. As the saying goes, if a Taoist moves a living thing and a tree dies, he must make it possible for the emperor to move the capital." Liu Weichen thought for a moment and said, "It's a good idea. Has the leader decided where to go?" Tang Feng replied: "Jinling (Jinling)" Today's Nanjing) before the Song Dynasty, many regimes established their capitals there, so the capital facilities there were relatively complete, and the natural barrier of the Yangtze River served as a barrier. The Jin army was good at horse fighting but not good at water warfare. The natural barrier of the Yangtze River was enough to stop them, just like It's the same as the army that blocked Cao Cao back then." Liu Weichen asked: "Then why didn't you tell me when I met you just now?" Tang Feng replied: "My position is too low, and the emperor won't listen even if I tell you." Liu Weichen asked: " What does the regiment leader plan to do?" Tang Feng said: "Join the high-ranking ministers and submit the memorial together." After lunch, Tang Feng began to write the memorial, stating the idea of moving the capital to Jinling to the emperor. After writing, Tang Feng did not submit it immediately. Instead of giving it to the emperor, he took it to see Li Gang. After the salute, the guests and hosts took their seats, and the servants brought tea. Li Gang said: "General Tang, we fought hard for several days and finally repelled the Jin army's attack. Why are you still worried? Tang Feng said: "Master Li, with all due respect and to put it bluntly, we paid for the Jin army's retreat this time. It's like a wolf chasing you. You throw meat to it, hoping that it won't retreat." If you chase you again, although the meat can temporarily satisfy the wolf, the wolf will continue to chase you after eating the meat and want more meat. Therefore, only by injuring or killing the wolf will it stop chasing you." Li Gang said: "General Tang, what you said makes sense, and I also advocate fighting. However, Tokyo is too close to the Yellow River. Once the Jin army goes south, it will be able to arrive very quickly." Tang Feng said, "I have a plan to change this situation." Li Gang After hearing this, his spirits were lifted and he immediately said: "I would like to hear the details." Tang Feng said: "We should suggest that the Holy Lord move the capital to Jinling, so that the capital will have two barriers, the Yangtze River and the Yellow River. The Jin army is good at horse warfare but not good at horse fighting. In a water battle, the natural dangers of the Yangtze River are enough to stop them. This way, Your Majesty will be safe, and the soldiers in front can let go and fight the enemy bravely." Li Gang agreed to Tang Feng's suggestion, and Tang Feng asked him to sign the memorial, then left. .
