The change of Nanjing's name in history is rooted in the likes and dislikes of the rulers. It is not only Nanjing that has also caused the change of other place names. After Song Tingping set up the Fang La uprising, he hated Jiangnan people for rebellion and the highest artistic accomplishment. The emperor Song Huizong then wrote on the place names: In the two active areas of Fang La, Luzhou was changed to Huizhou, and the original meaning of the "hui" was "bundled and bound"; Muzhou was changed to Yanzhou, which is even more self-explanatory. In contrast, in order to avoid the taboo of the country, Zhu Yuanzhang took the meaning of "Hai Ding Ze Boning" and changed Mingzhou to Ningbo, which was already "friendly".
