Qiandang Ancient Town is located in Kunshan, Suzhou. It is a national 4A tourist attraction and a famous historical and cultural town in China. But his fame is far less than that of Zhouzhuang in Jinxi, Kunshan. Only when you go into Qiandang Ancient Town and feel its small bridge and flowing people's ancient town, you will feel that it is no less than any ancient town. The buildings in the old town have not been specially renovated and expanded. The parallel pattern of land and water, the houses polished by the years, the rough stone roads, the alleys connected by the eaves, Gu Jian, the founder of Kunqu Opera, and Gu Yanwu, the thinker in the late Ming and early Qing Dynasties, are all worth visiting.
