Fishermen's songs (Liuhe fishermen's songs), a traditional music project in the fourth batch of Suzhou's representative list of municipal intangible cultural heritage projects. Fishery is a traditional industry in Liujiagang, Taicang (now Liuhe Town), and there are many fishermen who make a living by fishing at sea. The four-masted sailing boats used must hoist the sails high when going out to sea, and the nets must be lowered and raised according to the tide when fishing. In the process of labor, in order to coordinate actions, unify steps, and stimulate enthusiasm, fishermen's songs that are simple, easy to sing, catchy, and rich in regional characteristics have been produced. When the ship leaves the port, several crew members must use two slings to hook the bow and stern of the sampan with the pulley on the mast, and work together to lift the sampan tied to the stern onto the ship. In order to keep the sampan in a balanced state, they must sing "sampan hoisting songs". If the ship needs to move to a new fishing ground, it must winch the iron anchor weighing thousands of pounds that is thrown on the seabed onto the ship through a winch (i.e. a capstan). There are many crew members pushing the winch, and they must sing "pushing the winch songs" to coordinate their actions. The sails made of thick canvas on the boat are 40 to 50 meters long and about 10 meters wide, and there are dozens of bamboo poles passing through the mast. In the process of pulling the sail to raise it to the top of the mast, the crew members sing the "pulling sail song" and work together to complete the task. When fishing boats enter and leave the port, the captain will order the "head" (the crew member responsible for anchoring, lifting the anchor and measuring the water) to "fetch water", that is, measure the water depth to prevent running aground. The "head" will report the measured water depth data to the captain, and the captain will make a decision to move forward, slow down or stay anchor based on it. In the process of practice, it has gradually evolved into a custom of reporting the water depth with folk songs with a certain melody and charm, namely "fetching water songs". In the past, fishing at sea was divided into spring and winter. In summer and autumn, cargo transportation is also carried out. The cargo transported is often oil, which is loaded in oil baskets and oil drums and placed in the cabin. When unloading, the oil baskets and oil drums need to be lifted from the cabin and unloaded to the dock. In order to coordinate the actions of the crew and prevent the oil baskets from tipping over or sliding, the "Oil Basket Hoisting Song" should be sung. During fishing operations, the boat should be anchored at sea, with the left and right sides of the boat extending the net poles into the sea. When collecting the net, the heavy fishing net should be pulled onto the boat from the sea. If the catch is large, the pulley on the mast should be used to hoist the net bags onto the boat one by one. At this time, the "Net Pulling (or Hoisting Bag) Song" is needed to unify the command and hoist the nets quickly. All kinds of songs are sung in unison; there may be a lead singer or a chorus singer. Except for the specific lyrics of the lead singer or the command or encouragement, everyone basically sings "Hey!" "Hengyo!" and other echoing sounds. Only the "Water Hoisting Song" reports the water level, and only the "Boat Head" sings it. The fishermen's songs can be used to examine the state of fishery labor in history, reproduce the old fishermen's labor scenes at sea, and allow future generations to understand the labor life of fishermen. It is also an important material for studying the relationship between art and labor, and has certain historical and cultural value. The sonorous melody, catchy tune and rhythm of fishermen's songs have certain artistic value and are also valuable materials for composers. Fishermen in Liuhe, Fuqiao and Huangjing along the river in Taicang all sing songs. Among them, the "fishermen's songs" sung by fishermen in Liuhe Xingfu Fishery Society with the accent of Yancheng in northern Jiangsu are more charming and have the longest history. This has research value for the history of Taicang's fishery and cultural exchanges between the south and north of the Yangtze River.
