葭沚送大暑船是流传于浙江台州葭沚一带的传统民俗活动，通常在每年大暑节气前后举行，至今已有数百年历史。该习俗起源于当地先民对疫病的敬畏，相传大暑时节暑气最盛，瘟神易出没，人们便建造装饰华丽的 “大暑船”，用以送走瘟神、祈求五谷丰登、渔业兴旺和阖家平安，是典型的海洋与农耕文明结合的民俗信仰。
The Jiazhi Great Heat Boat Sending Ritual is a traditional folk activity prevalent in the Jiazhi area of Taizhou, Zhejiang Province. It is usually held around the Great Heat solar term every year and has a history of hundreds of years. This custom originated from the local ancestors’ awe of epidemics. According to legend, the Great Heat period sees the strongest summer heat and the easiest spread of plague. People built elaborately decorated “Great Heat Boats” to send away the plague god and pray for a bumper grain harvest, prosperous fishery and family safety. It is a typical folk belief combining marine and agricultural civilizations.
大暑船按照真实渔船的比例缩小制作，船身绘有各式吉祥图案，船上供奉神像、摆放祭品。活动当天，民众会抬着大暑船沿街区巡游，沿途锣鼓喧天、鞭炮齐鸣，队伍绵延数里，最后将船送至江边点火焚烧，任其随江水漂流入海，寓意将灾祸一并送走。2021 年，葭沚送大暑船被列入国家级非物质文化遗产代表性项目名录，是浙东地区极具地域特色的夏日民俗。
The Great Heat Boat is made in a scaled-down version of a real fishing boat, with various auspicious patterns painted on the hull and statues of deities and offerings placed on board. On the day of the activity, people carry the boat and parade along the streets, accompanied by deafening gongs, drums and firecrackers, with the procession stretching for miles. Finally, the boat is sent to the riverbank, set on fire and left to drift into the sea with the current, symbolizing sending away all disasters together. In 2021, the Jiazhi Great Heat Boat Sending Ritual was included in the National Intangible Cultural Heritage Representative List, and it is a highly distinctive summer folk custom in eastern Zhejiang.
