Nanxun district in Huzhou, Zhejiang province, has emerged as a key center for cultural exchange by promoting its unique fish-mulberry culture.

Fish-mulberry culture is deeply rooted in the region's 2,500-year-old Mulberry-Dyke and Fish-Pond System, a circular eco-agricultural model characterized as "raising silkworms with mulberry leaves, feeding fish with silkworm feces, and fertilizing mulberry trees with pond mud". It was recognized as a Globally Important Agricultural Heritage System by the UN Food and Agriculture Organization in 2017.

In 2025, Nanxun's Mulberry-Dyke and Fish-Pond Study and Cultural Exchange Base welcomed nearly 50,000 youth from across China and received around 3,000 inbound visits, generating over 100 million yuan ($14.52 million) in tourism revenue.

The base has meticulously sorted out documents to clarify the historical evolution of the Mulberry-Dyke and Fish-Pond System, enriching the content and significance of fish-mulberry culture.

Its efforts to preserve and promote fish-silk culture include collecting thousands of related artifacts and documents, publishing cultural books, and creating and staging traditional performances.

The base also serves as a comprehensive platform for cultural exchange, study tours, and eco-tourism, supported by a skilled team of experts and multilingual services.

By hosting events such as the Fish Culture Festival and offering hands-on experiences, the base continues to attract international visitors and garner global attention, fostering international partnerships and cultural dialogue.
