Near the Republican Street is the famous ancient town of Longxing. There are many images related to the "dragon" in the ancient town, such as the Dragon-Tibet Temple, the Dragon-Tibet Palace and the Royal Riverside, which all seem to be metaphorically related to the Royal family. According to "Jiangbei County Chronicle", Zhu Yuanzhang, the emperor of the Ming Dynasty, succeeded his eldest grandson to the throne after the death of the prince. Listening to the minister's decrees and cutting down the policy led to the mutiny. (In other words, the first time I learned about this period of history was to watch the popular TV drama "love through time and space") Emperor Jianwen disguised himself as a monk and fled to the adjacent waters of Taihong River (now the imperial river) via Sichuan Province. He stayed at Longxing Town at night. He got up at dawn and went to the bridge outside the town. When he found a pursuer, he returned to the Longzang Palace and hid in the stone cave under the shrine, where he pursued the soldiers to see the runken and dusty of the temple. For no one, Emperor Jianwen fled.
