The design is consistent across all three medals, featuring a circular shape. Within the crystal center, a logo or emblem is displayed. The logo includes Chinese characters and the words "LIN CLUB". The background of this central design is a vibrant blue, which contrasts effectively with the metallic frame surrounding the crystal. 

 

The color choices enhance the visual appeal of the single medal. For instance, the rose-gold finish on one adds a touch of sophistication, while the silver-toned finish on another offers a modern, sleek look, and the gold-toned finish of the third one offers a classic and prestigious aesthetic. The use of blue in the center is a consistent element that ties the designs together, ensuring that each single medal is easily recognizable. The crown detail at the top adds a touch of elegance. The blue ribbon is a perfect complement to the colors of the medal.
