A Beijing Hangzhou Grand Canal connects north-south transportation and thousands of cities and towns. In this treasure belt, Tangqi, an ancient town in Linping District, Hangzhou, Zhejiang Province, is an important waterway and a millennium civilization. It is like a bright pearl inlaid at the southernmost end of the Grand Canal. Wandering in the unique water street of Tangqi Town, the rich historical and cultural atmosphere is coming, and the splendid intangible cultural heritage culture has gained new vitality and become more and more prosperous in time. In Tangqi Town, the history of mulberry planting and silkworm rearing is very long. Qingshui silk floss originated from Tangqi is named after the water is clean and clear. It is the top grade of silk floss. It was well-known in the Tang Dynasty. In 2008, the production technology of Qingshui silk floss was listed in the second batch of national intangible cultural heritage list. In 2009, it was listed in the representative list of human intangible cultural heritage as part of "Chinese traditional sericulture and silk weaving technology". Due to the high production cost of manual silk floss, Qingshui silk floss once declined. Yu Caigen, a representative inheritor of national intangible cultural heritage projects, insisted on running his own Qingshui silk workshop and trained a number of inheritors through teaching apprentices and passing on skills. In 2020, Linping District newly identified two young district level representative inheritors, optimized the age structure of project inheritors, and laid a foundation for the protection and development of the project. In addition, relevant departments communicate with local silk and cotton production enterprises, encourage them to develop relevant cultural and creative products and intangible cultural heritage derivatives, further integrate into the construction of beautiful villages, and promote sericulture farmers and silk and cotton production farmers to increase their income. In 2014, the Grand Canal successfully applied for the world heritage, bringing new development opportunities to the Millennium ancient town. Over the past seven years, Tangqi has shown the world its profound historical heritage and cultural charm by constantly exploring the protection, inheritance and utilization of the excellent traditional culture of the Grand Canal.

In 2020, with the theme of Grand Canal cultural heritage, Linping district was successfully shortlisted for the establishment of provincial cultural heritage ecological protection zones in Zhejiang Province.
