The ancient sailing ships in Xiushan during the middle and late Qing Dynasty had a load capacity of about 320 tons {8,500 dan (164 jin per dan)}. The main purpose of shipbuilding was to engage in the shipping industry. With the opening of coastal ports, the maritime transportation industry gradually prospered. Before 1922, there were more than 190 ships of this type in Xiushan. The routes also extended to Fujian and Guangdong in the south, Qingdao and Dalian in the north, and as far as Southeast Asia, Japan, and Seoul, South Korea, providing valuable clues for the study of Zheng He's treasure ships. Production process: 1. Draw the drawings in proportion 2. Make various structural materials according to the drawings 3. First put on the main sampan, fix each beam head and the surrounding column (rib), erect the beam head, fix each beam head, bucket (bucket neck), sky raft, fix the tail wind beam and. 4. Put on other large bottom plates, transfer plates, and various jade ribs. 5. Install dry bore plate, head plate, operating system (rudder, steering wheel, rudder weight, etc.), anchoring system, sail system, sampan system (oar, oar, rudder, etc.). 6. Twist, copper oil and ash are mixed and polished in a ratio of 1:4. In the process, fill the gaps in the board with certain fillers according to the size of the board seams, and use various special nails to support the seams. 7. In order to prevent corrosion and insect infestation, the inside and outside of the boat are deeply brushed with copper oil. 8. Paint according to the color of each part of the boat, install the boat eyes, plant the mast, put up the sail, drop the anchor, put on the rudder, and hang the sampan.

Materials: The boat model can be made of camphor, fir, oil wood, small bamboo, etc. Tools: copper nails, paint, copper oil, tannin cotton cloth, axe, plane, chisel, saw and other woodworking tools. The history of ship model making is long, mainly loosely inherited by the society. It has now been passed on to Yang Yueguo of Langjizui, Gaoting Town, and he has set up a studio specializing in ship model making. The bird-shaped ship model of "Jin Shunli" produced is recorded in the "Picture Album of the First Zhoushan China Ship Model Competition".
