Great changes have taken place in golf from the Scottish era to the modern era. The original golf ball was sewn with feathers as the core and leather as the shell. It is not only difficult to craft, but also has a low rate of authenticity. However, badminton golf is not durable. Especially in rainy days, the sewing thread is easy to break, which often leads to the ball breaking in flight and the feather flying all over the sky. At the end of the 1850s, "rubber ball" appeared. This ball is made of rubber like eucommia gum.
