If culture is the "soul" of a city, then vinegar culture is the "soul" of Zhenjiang. Just like to visit Tiananmen Gate and climb the Great Wall when you go to Beijing, it is necessary to visit Zhenjiang Vinegar Culture Museum when you visit Zhenjiang. Looking at the history of China's century-old famous enterprise "Jiangsu Hengshun Group Co., Ltd. (formerly Hengshun Sauce and Vinegar Factory)" founded in Qingdaoguang in 1840, we tasted the taste of the original vinegar, understood the process of making vinegar, understood that vinegar must be brewed first, and the process of making vinegar on the 21st day and the origin of the Chinese character "vinegar", we learned a lot of knowledge.
