Under the influence of the exchange between Chinese and western scientific and technological thoughts,Wang Zheng from the Ming Dynasty designed a lever-type irrigation tool named Heyin.Its main structure consisted of a bucket,a ro-tating trough,a shaft,and ropes,which was delicately designed,efficient,and labor-saving.Illustrations of the New Crafting Vessels is the only source that preserves the image of Heyin,but its engraved edition,due to the systematic roughness and distor-tions in drawing,requires restoration through corrections based on manuscript copies.The name of Heyin suggests elegance,aes-thetic appeal,and practical utility,imbued with strong cultural and literary undertones,evidently reflecting Wang Zheng's thoughtful considerations after much deliberation.From the late Ming Dynasty to the mid-Qing Dynasty,Heyin was used in a small region in the north,and even served as a flood relief and fire extinguishing tool.However,due to its limited applicability,complex manufacturing process and high cost,Heyin gradually became disconnected from agricultural production and farmers'needs,and then faded out of historical stage,leaving a legacy in traditional agricultural culture.
