The craftsmanship of making Oujiang sailboats in Yunhe has a long history. The shipbuilding industry and water transportation industry along the Oujiang River have been developing continuously over thousands of years of history, creating Oujiang sailboats and nurturing a simple and profound boat gang culture. According to the "Yunhe County Chronicles", wooden sailboats were available in the upper reaches of the Oujiang River during the Spring and Autumn Period and the Warring States Period. The Zhejiang Provincial Archives has a record: In the early years of the Republic of China, "8,000 ships in the Oujiang River, an average of 250 ships arrived at the Yongjia terminal every day". Many villages along the river in Yunhe, such as Chishi, Longmen, Jinshuitan, and Shipu, have a long history of sailboat manufacturing. The production of a wooden sailboat is completed through many complicated processes such as design, material preparation, carpentry, and painting, and exquisite woodworking skills are permeated in each process. The special geographical environment factors of the upper reaches of the Oujiang River with many rapid waters have created the special structure and modeling characteristics of the Oujiang sailboat. The intangible cultural heritage Oujiang sailboat has a pointed hull at both ends and is in the shape of a wooden shuttle. People in the entire Oujiang River basin vividly call it "sparrow boat" or "舴艋 boat". The unique sail design further reflects its technical achievements. As a production and living tool closely related to the people along the Oujiang River, the Oujiang sailboat is the crystallization of traditional culture and exquisite woodworking skills.
