A century-old vinegar factory in Zhenjiang City of east China's Jiangsu Province has virtually transformed itself into an immersive industrial tourism destination while also maintaining the main business of vinegar production, drawing increasing numbers of visitors with its national intangible cultural heritage -- time-honored vinegar brewing techniques.

Inside the factory, visitors can watch the vinegar being brewed, try bottling vinegar themselves, explore the intelligent production workshop, and even taste the vinegar.

"I tried making vinegar myself. It was great. I took photos and experienced it firsthand. It was really a good experience," said Zeng Huifang, a tourist.
