The model is a model performer after assembling the products of the prosthesis assembly factory. Its real purpose should be to help disabled friends to build up the hope of life and the goal of pursuit. Some disabled friends like to use the model demonstration results of the prosthesis assembly factory to choose the manufacturing technology, product quality, etc., which is a very irrational way of judgment.

The beauty of a disabled friend's walking with a prosthesis is a comprehensive parameter. It has an inseparable relationship with disabled friends' physique, age, conditions of disabled limbs, materials and performance of prosthesis, training time, perseverance and correct training methods. Model - the assembler can deliberately train or search, but the consumer must be very clear that you are yourself - model can not represent yourself. You can walk better than a model, as long as you have the right conditions. Otherwise, you will feel lost after the prosthesis is is assembled.

The walking quality of models does not completely represent the manufacturing technology and product quality of prosthetic manufacturers. It is the rational way of thinking for disabled friends to objectively view the dialectical relationship between the walking effect of models in assembly plants and their actual assembly results.
