The invention relates to a simple manufacturing method for long-term preserving softened human anatomy viscous specimens. The method comprises the following steps of injecting 4% of formaldehyde solution stationary liquid into vein from artery, flowing out and dipping; taking out and dipping into 50% of alcohol; dissolving 15% of polystyrene foam into chloroform, adding 10% of dibutyl phthalate, injecting a curing agent into the vein from artery, flowing out, dipping the specimen, dipping in 100% of alcohol after being cured, removing the residual smell, removing the residual water and shaping. By utilizing the method, the defects that the viscous in the conventional plasticized specimen is easy to shrink, cannot be kept in the original morphology and cannot be used for teaching are overcome; the specimen is soft, cannot be broken or recovered to the original shape even being distorted or compressed, is short in manufacturing process and low in cost, needs no special equipment, and can be manufactured at norm
