When choosing temu when there is no corresponding material, we can consider it based on two aspects.

First, we can consider the properties of the product, so that we can choose the closest material, such as the material's hardness, strength, density and other indicators.

Second, we can consider using similar materials as a substitute based on experience and practice. Some similar substances can bring us better substitutes, which requires the support of experience and professional knowledge. Therefore, we can use the above two considerations to make appropriate choices for temu that has no corresponding material.
